Additionally, it falls under the category of ultra LOW on-resistance devices based on Advanced Process Technology, making it a building block of the electronic applications where fast switching is a major concern.
In this post, I'll cover each and everything related to this transistor, its main features, working, pinout, and applications. Let's get down to the nitty-gritty of this tiny component.
Introduction to IRF3205
- IRF3205 is an N-Channel HEXFET Power MOSFET that is mainly based on Advanced Process Technology and used for fast switching purpose.
- International Rectifier has introduced this device with the aim to generate extremely low on-resistance per silicon area.
- This power MOSFET is known as the voltage controlled device that mainly contains three terminals called:
- The voltage at Gate Terminal is used to handle the conductivity on other two terminals.
- The low thermal resistance and operating temperature around 175°C make this device an ideal choice for commercial industrial applications, providing power dissipation of around 50 watts.
- This Power MOSFET differs from the normal MOSFET, where former comes with gate layered with thick oxide and can experience high input voltage while the later comes with thin gate oxide without the ability to withstand high voltage i.e. applying high voltage will drastically affect the overall performance of the device.
- It features benchmark high package current ratings - appropriate for high power DC motors, power tools, and industrial applications.

- Movement of electrons plays an important role in the current flowing from drain to source terminal.
- The output current is highly dependent on the voltage applied to the gate terminal.
Working
- The gate, source and drain in this MOSFET are analogous to the base, collector, and emitter in the BJT (Bipolar Junction Transistors)
- The source and drain are made up of n-type material while component body and the substrate is made up of p-type material.
- Adding silicon dioxide on the substrate layer gives this device a metal oxide semiconductor construction.
- It is a unipolar device where conduction is carried out by the movement of electrons.
- An insulating layer is inserted in the device that makes gate terminals separated from the entire body. The region between drain and source is called N-channel that is controlled by the voltage present at the gate terminal.
- MOSFET stays ahead of the curve when they are compared to BJT as the former needs no input current to control a large amount of current on remaining two terminals.
- Applying a positive voltage at this MOS structure will change the charge distribution in the semiconductor where holes present under the oxide layer deal with the force, allowing the holes to move downward.
- It is important to note that, the bound negative charges are connected with acceptors atoms that are mainly responsible for flocking the depletion region.
- The electrons, if applied with abundance, will help in increasing the overall channel conductivity, changing the substrate into the N-type material.
IRF3205 Proteus Simulation
- As I have told you earlier, IRF3205 is an N-channel Mosfet used for fast switching, that's why it's an ideal selection for designing H-Bridge.
- I have designed this Proteus Simulation where I have converted DC voltage into AC and if you look at it closely then I have used IRF3205 MOSFET in the H-Bridge:
- Moreover, I have used IRF5210 for the counter P-Type Mostel in H-Bridge.
- If you run your simulation then you will get AC sine wave in your oscilloscope, as shown in below figure:

Introduction to IRF4905
- IRF4905 is a P-Channel HEXFET Power MOSFET available in a TO-220AB package and is based on Advanced Process Technology.
- It comes with three main terminals called drain, gate and source that are analogous to the emitter, base, and collector in the BJT (Bipolar Junction Transistors)
- It is a unipolar device where only one charge carriers i.e. holes are responsible for the current conduction.
- There are two types of MOSFET available for the development of electronic projects i.e. P channel and N channel both make use of single charge carriers where former contain holes as the major charge carriers and later contain electrons as the major charge carriers.
- This device falls under the category of Power MOSFET, different from normal MOSFET, where former contains thick gate oxide that can withstand high input voltage while the later comes with thin gate oxide, making it unable to bear high input voltage.
Working of IRF4905
- In this MOSFET transistor, gate plays a vital role to handle the conductivity in the channel between drain and source. As it is a P-Channel - holes will be responsible for the current conduction.
- In this components, the body and substrate are composed of N-type material while the drain and source are composed of P-type material - Laying out an exact oppositive composition as compared to N-Channel MOSFET.
- Following figure shows the internal construction of IRF4905.
- Applying negative voltage at the gate terminal will move the oxide layer downward in the substrate layer with a strong repulsive force, allowing positive holes to be accumulated around the gate region.
- The negative voltage applied at the gate terminal attracts the holes, helping to produce the p-type conducting channel using n-type substrate material.
