1N5822 Schottky Diode Pinout, Specifications, and Datasheet

Hello Guys! Hope you’re well today. Happy to see you around. I welcome you on board. In this post today, I’ll detail the Introduction to 1n5822. The 1n5822 is a Schottky diode that comes with a low forward drop voltage around 0.525V which means it needs 0.525 voltage to conduct the current in forward biased direction. It supports a load under 3A and is an ideal pick for switching applications with low current ratings. And the 40V is the maximum repetitive peak reverse voltage Vrrm of this tiny device. Just bear with me for just 2-min as I’ll be discussing the datasheet, Pinout, specifications, and applications of this tiny little device. Let’s get started.

Introduction to 1n5822

• 1n5822 is a Schottky diode, also known as a hot-carrier diode, mainly used in fast-clamp diode switching applications. It is made up of semiconductor material and carries low forward drop voltage.
• The small voltage drop occurs across the diode terminals when current flows through the diode.

• Though both normal diode and Schottky require 2V DC source to power these components, the Schottky diode utilizes 0.3V out of 2V, leaving only 1.7V to power the diode while the normal diode uses 0.7V out of a 2V DC source, leaving 1.3V to power the diode.

• Schottky diode is also called hot-carrier diode because electrons carry low energy when they are present on the semiconductor material in an unbiased condition.
• This results in the formation of a barrier through which electrons cannot flow, the reason it’s also called the Schottky Barrier diode or hot carrier diode.

1n5822 Schottky Diode Construction

• The 1n5822 Schottky diode is constructed by the combination of semiconductor material with metal, forming a barrier.
• The metals used in this case are tungsten, chromium, platinum, molybdenum, and silicides.
• And the n-type silicon is the commonly used semiconductor material. The resulting diode carries a very low forward voltage drop and is capable of very fast switching.
• The metal used behaves as an anode or positive side of the diode and n-type semiconductor (with a colored band) is used as a cathode or negative side of the diode. In this case, the conventional current will flow from the anode metal side to the cathode semiconductor side.
• The forward voltage of the diode depends on the nature of the metal and semiconductor you pick for the formation of that diode.
• Though both n-type and p-type semiconductors are used to form a Schottky diode, the p-type semiconductors result in very low forward voltage compared to n-type semiconductors, the reason p-type semiconductors are rarely used to form the Schottky diodes.

• In Schottky diodes less energy is wasted as heat as they possess low forward voltage drop, making them an ideal pick for the applications that are sensitive to efficiency.
• Plus, they are also used in photovoltaic systems to keep the batteries from discharging in solar panels at night.
• A control circuit or MOSFET can replace Schottky diodes in cases where less power dissipation is needed.

Just stay with me for a little while as I’ll be discussing the complete introduction to MUR460 covering pinout, features, working, and applications of this component. Let’s get started.

Introduction to MUR460

• The MUR460 is a diode used as a rectifier in high frequency and freewheeling applications, in switching mode converters, and as an inverter in telecommunication.
• When this p-n junction diode is used as a rectifier it coverts AC signals to DC signals. The rectifier diode provides an alternating voltage that changes with respect to time.

• The p-n junction diode blocks current in reverse biased condition and allows the current to flow in forward biased condition only. Simply put, the p-n junction diode allows current to flow in one direction only and it blocks the current flowing in the opposite direction.
• MUR460 comes with a working peak reverse voltage and a maximum repetitive peak reverse voltage of 600V. The maximum average forward rectified current is 4A. And the operating junction temperature range is -65 to 175 C.

MUR460 Datasheet

• This diode rectifier comes with two terminals called anode and cathode.
• The anode side is positive through which current enters the diode and the cathode side is negative through which current leaves the diode and current moves from the anode terminal to the cathode terminal.

 

MUR460 Working

• The working of this component is simple and straightforward. When the voltage is applied to the rectifier diode in such a way the negative terminal of the battery is attached with the n-type semiconductor and the positive terminal of the battery is connected to the p-type semiconductor material, in this condition the diode is forward biased.

• In this forward biased condition, the free electrons available in the n-type region of the semiconductor experience a repulsive force, and a large number of holes present in the p-type semiconductor also experience a repulsive force.

• In this case, the electrons due to this repulsive force start moving from the n-type region to the p-type region and the holes in the p-type region start moving to the n-type region.
• And the conduction is carried out due to these charge carriers i.e. holes in the p-region and the electrons in the n-region.
• As this conduction is the result of the movement of free majority charge carriers in the diode, the reason the current in the forward biased condition is also called the majority current.

• Available in Tape and Reel

LM2575 Buck Converter Datasheet, Pinout, Features, Applications

Hi Guys! Glad to see you around. I welcome you on board. In this post today, I’ll walk through the Introduction to LM2575. LM2575 is a step-down voltage regulator mainly used to step down the voltage. It is also known as a buck converter and is used to drive load under 1A. In the customized output version of the buck converter, you can set the output voltage as you like better. It comes with an extremely good load and line regulation and is available in fixed output voltages with 3.3V, 5V, and 12V. I suggest you read this post all the way through, as in this post I’ll detail the Introduction to LM2575 covering the datasheet, pinout, features, and applications of this component LM2575. Let’s get started.

Introduction to LM2575

• LM2575 is a voltage regulator and simplified version of switching power supplies that carry all functions required to step down the voltage in the circuit.
• This buck converter is incorporated with an integrated switch that can support load under 1A.

• LM2575 carries an excellent load line and load regulation. It comes in two versions: fixed output voltage version with voltage 3.3V, 5V, 12V, and adjustable output version that gives the ability to pick your desired output.
• It is also called the DC-to-DC power converter employed to step down the voltage from its input supply to its output load. The current increases during this voltage regulation.
• This regulator is integrated with a fixed-frequency oscillator of about 52 kHz and an in-built frequency compensation method.

Introduction to TIP42

Hi Guys! Thank you for clicking this read. Hope this finds you well. In this post today, I’ll document the Introduction to Tip42. Tip42 is a medium power silicon transistor mainly used for switching and amplification purpose. It belongs to the PNP transistor family and comes in the TO-220 package. The collector current is 6A which signals it can support load under 6A. Both collector-base and the collector-emitter voltages are 40V. And the only 5V is required to initiate the transistor action as the emitter-base voltage is 5V. The power dissipation is 65W which defines the amount of energy released during the working of this transistor. The storage junction temperature is -65 to 150C and transition frequency is 3MHz. Just stay with me for 2-min as I’ll be discussing the main features, pinout, datasheet, and applications of the device Tip42. Let’s jump right in.

Introduction to TIP42

• • Tip42 is an epitaxial medium power silicon transistor mainly used for switching and amplification purpose. It falls under the category of PNP transistor and comes with current gain ranging from 15 to 75.
  • This current gain demonstrates the capacity of transistor it can amplify the current. It’s a ratio between the output current and input current.
  • Tip42 is a bipolar transistor which means two charge carriers are used in the conductivity process inside the transistor.
  • Both electrons and holes take part in the conductivity process. And in this case of PNP transistor, holes are majority carriers. And electrons are minority carriers in the case of NPN transistors.

• This PNP transistor contains three terminals called the emitter, base, and collector. All these terminals carry different functionality and different doping concentration.

• This different doping concentration is the main reason this bipolar transistor is not symmetrical. The external circuit is connected with the transistor through these terminals.
• Tip42 is composed of two p-doped layers and one n-doped layer. The n-doped layer is sandwiched between the two p-doped layers. The two p-layers represent the collector and emitter terminals and the n-layer represents the base terminal. The N sign shows, a negative voltage is applied on the base terminal to trigger and start the transistor action.
• This bipolar transistor controls the small input current and produces the large output current, the reason these devices are called current-controlled devices because two charge carriers are used for conductivity in contrast to FETs(field effect transistor) which is unipolar voltage-controlled devices. Where conductivity is carried out with only one charge carrier.

 

TIP42 Features

The following are the main features of transistor BC538.

• Package: TO-220
• Material: Silicon
• Type – PNP
• Emitter-Base Voltage: 5 V
• Collector-Base Voltage: 40 V
• Collector-Emitter Voltage: 40 V
• Collector Dissipation: 65 W
• Collector Current: 6 A
• Transition Frequency: 3 MHz
• Current Gain (hfe): 15 to 75
• Storage Junction Temperature: -65 to +150 °C

  These are the main features and absolute maximum ratings of the device Tip42. Make sure you don’t apply these ratings for more than the required time, otherwise it will harm your device reliability.

• Plus, make sure your ratings don’t exceed these absolute maximum ratings while you’re working with the device, otherwise they will badly damage the device and thus the entire project.

• Both collector-emitter and collector-base voltages are 40V while the emitter-base voltage is 5V which projects you need to apply 5V to initiate the transistor action.
• The Collector current is 6V which indicates this transistor can support load under 6A. The transition frequency is 3MHz and power dissipation is 65W which is the amount of energy released during the working of this transistor.

• DC common-emitter current gain ranges from 15 to 75. It is a ratio between collector current and base current. This describes the capacity of transistors it can amplify the current. This is a relation between output amplified current to input small current.
• Another important current gain is the common-base current gain which is a ratio between collector current and emitter current and its value is always less than one. Normally ranges from 0.5 to 0.95.
• The small current at one pair of terminals is used to produce large current across other pairs of terminals of the transistor and this process is used for amplification purposes.
• It is important to note that the PNP transistors are less likely to employ for amplification purposes than NPN transistors. Because the mobility of electrons in the NPN transistor is far better and quicker than the mobility of holes in PNP transistors.

 

TIP42 Pinout

The Tip42 consists of three main terminals called: 1: Base 2: Collector 3: Emitter The following figure shows the pinout diagram of Tip42.

• The collector terminal is lightly doped and the emitter terminal is highly doped in contrast to the other two terminals.
• The collector terminal is 10-times lightly doped than the base terminal. And this transistor is manufactured in such a way, the collector side covers the entire emitter terminal area.
• The base terminal is responsible for the entire transistor action.
• This base terminal acts like a control valve that controls the number of holes in the case of the PNP transistor and the number of electrons in the case of NPN transistor.

• When 5V is applied at the base terminal, it gets biased and starts the transistor action where current moves from emitter to collector terminal which is the opposite in the case of NPN transistors where current moves from collector to emitter terminal. And in both cases base terminal controls the amount of current passing through it.

TIP42 Datasheet

Before you apply this device into your project, scan through the datasheet of the component that helps you get a hold of the main characteristics of the device. You can download the datasheet of Tip42 by clicking the link below.

TIP42 Applications

Tip42 is used in the following applications.

• Used for switching and amplification purpose.
• Used to drive load under 6A.
• Incorporated in the motor control circuit
• Employed in H-bridge circuit
• Incorporated in the voltage regulator circuit

Introduction to TIP42C

Hi Friends! I welcome you on board. Happy to see you around. In this post, I’ll detail the Introduction to Tip42c. Tip42c is a medium power transistor mainly used for amplification and switching purpose. It is made up of silicon material and falls under the category of PNP transistors. The voltage across collector and emitter terminals is 100V and the voltage across base and collector terminals is 100V. The 5V is the voltage across base and emitter terminals which projects the value of voltage required to bias this transistor. The 6A is collector current which indicates the value of loads this transistor can support. Just bear with me for a little while as I’ll be documenting the main features, pinout, applications, and datasheet of this tiny component Tip42c.

Introduction to TIP42C

• Tip42c is a PNP medium power bipolar transistor mainly used for switching and amplification purpose.
• It is composed of silicon material and comes in the TO-220 package.

• It comes with three pins called the emitter, base, and collector. These pins are also known as transistor terminals that are connected with the external electrical circuit.
• The small input current across one pair of terminals is used to generate large output current across other pairs of terminals.
• Tip42c contains three layers where two are p-doped silicon layers and one is an n-doped silicon layer. The n-doped layer represents the base terminal where negative voltage is applied to start the transistor action. The two p-doped layers surround the n-doped layer.

• As this bipolar transistor controls the small current to produce large current, the reason bipolar transistors are considered as a current-controlled device in contrast to FETs(field effect transistor) which is a unipolar transistor (conductivity happens due to one charge carrier) that are voltage-controlled devices.
• Two current-gains are important while studying bipolar transistors. One is a common-emitter current gain which ranges from 15 to 75 in this case and common-base current gain which is a ratio between collector current to emitter current, this is normally called alpha.

Its value is always less than 1, commonly lies from 0.90 to 0.95 but more often than not its value is taken as unity.  

TIP42C Features

The following are the main features of device Tip42c

• Name: TIP42C
• Package: TO220
• Material used: Silicon
• Type: PNP
• Power Dissipation: 65 W
• Collector-Base Voltage = Vcb: 100 V
• Collector-Emitter Voltage = Vce: 100 V
• Emitter-Base Voltage = Veb: 5 V
• Collector Current = Ic : 6 A
• Operating Junction Temperature = Ti:  -65 to 150 °C
• Transition Frequency = ft: 3 MHz
• Common-emitter current gain = hfe: 15 to 75

These are the main features and the power ratings of the transistor Tip42c. Don't apply these ratings for more than the desired time, else they will influence the device reliability.

• The Tip42c is a bipolar transistor which means two charge carriers are used for the conduction process inside the transistor. Both electrons and holes are used for the conductivity, however, holes are the majority carriers and electrons are the minority carriers. Which is the opposite in the case of NPN transistor where electrons are the majority carriers and holes are minority carriers.
• This PNP transistor comes in TO-220 package with collector current 6A which demonstrates it can support the loads under 6A.

• The junction temperature ranges from -65 to 150C and the transition frequency is 3MHz which is a measure of the transistor’s high frequency operating characteristics. It is denoted by ft.
• The common-emitter current gain stands from 15 to 75 which is the capacity of the transistor it can amplify the small input current. It is called beta and is a ratio between output collector current to input base current.

• And the only 5V is required to start the transistor action because 5V is the voltage across emitter and base terminals.
• It is important to note that this PNP transistor is not preferred over its counterpart NPN transistor because the mobility of electrons in the NPN transistors is quicker and better than the mobility of holes inside the PNP transistor.
• Moreover, in NPN transistors the current flows from the collector side to the emitter side in contrast to PNP transistors where current moves from the emitter side to the collector side.
• The 65W is the power dissipation that indicates the energy released when this transistor starts working in the electrical circuit. This varies from transistor to transistor.

TIP42C Pinout

The Tip42c contains three terminals named: 1: Base 2: Collector 3: Emitter The following diagram shows the pinout of the transistor Tip42c.

2SB772 Transistor Pinout, Features, Datasheet & Applications

Hello everyone! I welcome you on board. Hope you’re well. In this post today, I’ll detail the Introduction to 2sb772. 2sb772 is a PNP transistor that comes in the TO-126 package. It is mainly used for amplification and switching purposes. This is a bipolar junction transistor which means the conductivity is carried out by two charge carriers i.e. holes and electrons. And it comprises of two junctions where the base-emitter junction is forward biased and the base-collector junction is reverse biased in forward active mode. In this post, I’ll be discussing the working principle, pinout, datasheet, physical dimensions, power ratings, and applications of the device 2sb772. Let’s get started.

Introduction to 2SB772

• The 2sb772 is a medium power PNP bipolar junction transistor mainly employed for switching and amplification purpose.
• It comes with three main terminals called the emitter, collector, and base. All these terminals come with different functionality and different doping concentrations.
• The emitter side is highly doped in contrast to the other two terminals and the collector is lightly doped. The base terminal is 10-times highly doped compared to the collector terminal.
• 2sb772 is a semiconductor device made up of silicon material and it consists of three layers. Where one is an n-doped layer that stands between two p-doped layers.

• The n-layer signals the base terminal and indicates that negative voltage supply is required to bias the base terminal and start the overall transistor action.
• As this is a bipolar transistor, both electrons and holes play a vital role in the conductivity process.

• And holes are majority carriers while electrons are minority carriers in this case in contrast to NPN transistors where electrons are major carriers and holes are minority carriers.
• The bipolar transistors like this 2sb772 are the building blocks of modern electronics.
• In some cases, however, the vacuum tubes are preferred over bipolar transistors since the mobility of charge carriers is far better in vacuum tubes which is suitable for high-power high-frequency applications like on-air television broadcasting.

2SB772 Datasheet

Before installing this component into your project, have a quick look at the datasheet that helps you get a hold of the main characteristics of the device. Click the link below and download the datasheet of 2sb772.

2SB772 Pinout

The 2sb772 carries three main terminals known as 1: Emitter 2: Collector 3: Base The following figure shows the pinout diagram of the 2sb772 transistor.

• All these terminals are used for the external connection with the circuit. The emitter side carries the overall transistor current.
• And in this PNP transistor current flows from the emitter to the collector terminal due to the movement of major charge carriers i.e. holes.
• While the current flows from the collector to the emitter terminal in the case of NPN transistors due to the mobility of electrons.

2SB772 Working Principle

• The working principle of this transistor is simple and quite similar to NPN transistors. In both NPN and PNP transistors, the base pin is mainly responsible for the overall transistor action.
• And when a positive voltage is applied at the base terminal it gets biased and current flows due to the movement of holes.

• When there is no current available at the base terminal, the transistor is turned ON and in that case, both collector and emitter pins are forward biased.

• And when there’s current present at the base terminal, the device is turned OFF and both emitter and collector terminals are reverse biased.
• Unlike other transistors, bipolar transistors are not symmetrical. Different doping concentrations of both emitter and collector sides are responsible for the lack of symmetry inside bipolar junction transistors.
• Moreover, if we exchange the collector and emitter terminals, the common-emitter gain and common-current values will be less than they are normally observed.
• The common-emitter current gain is called beta and is also known as the amplification factor. In this case, the amplification factor stretches from 30 to 300. This factor determines the amount of input current this transistor can amplify.

2SB772 Power Ratings

The following table shows the absolute maximum ratings of 2sb772.

Absolute Maximum Ratings BC639
No.	Rating	Symbol	Value	Unit
1	Collector-Emitter Voltage	Vce	30	V
2	Collector-Base Voltage	Vcb	60	V

5	Current Gain	hfe	30 to 300
6	Power Dissipation	Ptot	12.5	W
7	Storage Temperature	Tstg	-65 to 150	C

• The collector-base voltage is 60V while the collector-emitter voltage is 30V. And the emitter-base voltage is 5V which means it requires a total 5V to start the transistor action and bias this device.
• The power dissipation is 12.5W which determines the amount of energy this device releases during the working of this component. Storage temperature lies from -65 to 150 C and the junction temperature is 150C.
• While working with this device make sure your ratings don’t exceed these absolute maximum ratings, else you’ll risk the component and thus the entire circuit.

• Also, if you apply these ratings for more than the required time, they will affect device reliability.

TIP41C Transistor Pinout, Features, Datasheet & Applications

Hi Friends! Welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to Tip41c. Tip41c is an NPN transistor that comes in the TO-220 package and is mainly used for amplification and switching purposes. It’s a high switching speed device with improved current gain and a high collector current around 6A that indicates the value of load this device can support. Both collector-base and collector-emitter voltages are 100V (higher than other bipolar transistors) and the emitter-base voltage is 5V which shows the only 5V is required to bias this component. Just stay with me for a little while as I’m going to detail the pinout, datasheet, applications, power ratings, working principle, and physical dimensions of this tiny device. Let’s jump right in.

Introduction to TIP41C

• Tip41C is an electronic tiny device mainly used for switching and amplification purpose. It belongs to the category of NPN transistor and comes with high power around 65W, which is the amount of energy released during the working of this transistor.
• This NPN transistor comes with three pins, also known as terminals, called the emitter, collector, and base.
• The small input current across one pair of terminals is used to produce a large current across other pairs of terminals. This process is used for amplification purposes.

• Tip41c is composed of three layers. One is a p-doped layer and the other two are n-doped layers that are made up of semiconductors (silicon material).
• The p-doped layer sits between the two n-doped layers. And the p-doped layer is the base terminal and the P sign shows positive voltage is applied at the base terminal to start the transistor action.
• This device is composed of two junctions. One is the base-emitter junction that is forward biased and the base-collector junction that is reverse biased in forward active mode.

• The collector current is 6A which is much higher than other bipolar transistors available in the market. This current defines the amount of load this device can support.
• And common-emitter current gain stretches from 15 to 75 which is the capacity of the transistor it can amplify the input current. It is a ratio between collector current and base current.
• The transistor frequency is 3MHz which demonstrates how the current gain of the transistor is influenced by the input frequency.
• This device controls the low input current and produces high output current, the reason this device is called a current-controlled device.
• This is a bipolar transistor which means two charge carriers are used for the conductivity process i.e. electrons and holes. The electrons are major carriers in NPN transistors and holes are major carriers in PNP transistors.

TIP41C Pinout

The Tip41c comes with three terminals named: 1: Base 2: Collector 3: Emitter The following figure shows the pinout diagram of Tip41c.

• This device is manufactured in such a way, the collector side covers the entire emitter area, making electrons difficult to escape without being collected by the collector terminal.
• All these pins come with different doping concentrations. The collector side is lightly doped and the emitter side is more doped compared to both base and emitter pin.
• The collector pin is 10-times lightly doped compared to the base terminal. These pins are used for external connections with the electrical circuit.

TIP41C Working Principle

• No matter the bipolar transistor you pick, the base pin is responsible for the transistor action in every bipolar transistor. When a positive voltage is applied at the base pin, it gets biased, initiating the transistor action.
• And the current starts flowing from the collector to the emitter terminal in contrast to the PNP transistor where current flows from emitter to collector terminal.
• The base pin works like a control valve that controls the number of electrons in this NPN transistor and the number of holes in the PNP transistor.
• The bipolar transistors are not symmetrical. The lack of symmetry is caused by different doping concentrations of collector and emitter terminals.

• The two most common current gains are used to demonstrate the nature and current amplification capability… one is a common-emitter gain that 10 to 75 in this case which is a ratio between the collector and base current.

• It’s is also known as the amplification factor. This factor signals the capacity of transistors it can amplify the small input current. This factor is called beta.
• Another important factor is a common-base current gain which is a ratio between collector and emitter current. The value of this gain is always less than 1. Most likely stretches from 0.5 to 0.95.

TIP41C Power Ratings

The table below shows the absolute maximum ratings of Tip41c.

Absolute Maximum Ratings of Tip41C
No.	Rating	Symbol	Value	Unit

5	Current Gain	hfe	15 to 75
6	Power Dissipation	Ptot	65	W
7	Storage Temperature	Tstg	-65 to 150	C

• You can see from the table, collector-base and collector-emitter voltages are 100V and the emitter-base voltage is 5V which means it requires 5V to start the transistor action.

• Total power dissipation is 65W and common-emitter current gain lies from 15 to 75 that defines the capacity of transistor it can amplify the input current. The transition frequency is 3MHz and the storage temperature stands from -65 to 150C.

• MJE5180
• 2SD1895
• MJE5181
• BC911
• BD711

Cross-check the pinout of alternatives before you incorporate them into your project. It’s likely the pinout of the alternatives doesn’t exactly match with the Tip41c pinout. To remain on the safe side and to avoid any hassle later, double-check the pinout of the alternatives. The complementary PNP transistor to Tip41c is Tip42c.
