Introduction to IRF540

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of guys about Introduction to IRF540. It is basically an N-Channel power Metal Oxide Silicon Field Effect Transistor (MOSFET) and operates in enhancement mode. MOSFET is a lot sensitive in comparison to an FET (Field Effect Transistor) due to its very high input impdence. IRF540 can perform very fast switching as compared to the normal transistor. It is based on HEXFET technology and operates on the temperature ranging from -55 degrees celsius  to 175  degree celsius. If we need some switching application between different signals or to perform any of amplification process, MOSFET IRF540 will be the best option in this case because it can perform very fast switching as compared to the similar general transistors. It has a very wide range of applications in real life e.g. high power switching drivers for high speed, switching regulators, relay drivers, switching converters, motor drivers. Note:

Introduction to IRF540

IRF540 is an N-Channel powered MOSFET used for very fast switching operations as well as for amplification processes. It operates in enhancement mode. Its input impedance is quite high as compared to the general transistor so, its a lot sensitive in comparison to them. It has a lot of applications in daily life for example, switching regulators, relay drivers, switching converters, motor drivers, high speed power switching drivers etc. You should also have a look at other MOSFETs and can compare their values with IRF540.

1. IRF540 Pinout

• IRF 540 has three pins in total named as:
  1. Drain
  2. Gate
  3. Source
• So, when we apply signal at the Gate of IRF540, then its Drain and Source got connected.
• All of the IRF540 pins along with their names and symbol are given in the table shown below.

 

IRF540 Pinout
Pin#	Name	Symbol	Type	Function
1	Gate	G	P-Type	Controls the current between Drain & Source
2	Drain	D	N-Type	Electrons Emitter
3	Source	S	N-Type	Electrons Collector

 

2. IRF540 Pin Diagram

• A properly labeled diagram helps in better standing of the user.
• So, I have provided the completely labeled diagram of IRF540 pins configuration.
• The diagram of this MOSFET is shown in the figure below.

3. IRF540 Dimension

• Three dimensions e.g. length width and height of IRF540 module is provided along with their units in the table shown below.

4. IRF540 General Specifications

• The general specifications e.g. configuration, channel type, channel mode, pin numbers, package and category are provided in the table shown below.

5. IRF540 Ratings

• The current, voltage and power ratings of IRF 540 are provided along with their values and System International (SI) units are provided in the table shown below.

6. IRF540 Working Principle

This section of the tutorial will elaborate about the basic working principle on which IRF540 works. IRF540 works on a pretty simple principle. Its has three kinds of terminals e.g. Drain, Gate and Source. When we apply any of the pulse at its Gate terminal, its Gate and Drain gets short i.e. they make a common connection with each other. When the Gate and the Drain gets short, only then we will be able to obtain the desired results otherwise it will produce unnecessary or unwanted results.

7. IRF540 Applications

• The applications associated with IRF540 are given below.
• It can be used as switching converters.
• We can use it as relay drivers.
• It can also be used as high speed switching drivers.
• We can use it as motor drivers.
• It can be used for fast switching and for amplification processes.

8. IRF540 Proteus ISIS Simulation

• I have made a Proteus simulation for DC motor control using IRF540.
• The screenshot of the simulation is provided in the figure shown below.

• The running form of the above simulation is shown in the figure below and you can see in the below figure that as we closed the switch, motor got running.

• When you run the simulation the motor will change its color i.e. blue, as shown in the figure above.
• After running the simulation as you press the button encircled in the above figure, the motor will start to rotate.
• I have another simulation in Proteus ISIS for DC motor control using IRF540 and Arduino UNO.
• The simulation is shown in the figure below.

• If you have a look at the above simulation then you can see, we are sending signal from Arduino to Optocoupler.
• IRF-540 is connected at the output of Opto-coupler.
• Moreover, we have used 1N4148 which is a diode and is used for security reasons and is not allowing the current to flow in opposite direction.
• The source code written in Arduino software is given below.

int MotorInput = 2;
int MotorOutput = 7;

void setup() 
{
    pinMode(MotorInput, INPUT_PULLUP);
    pinMode(MotorOutput , OUTPUT);
}

void loop() 
{
    if(digitalRead(MotorInput) == HIGH)
    {
      digitalWrite(MotorOutput, HIGH);
    }
    if(digitalRead(MotorInput) == LOW)
    {
      digitalWrite(MotorOutput, LOW);
    }
  
}

• You need to just copy and paste the above code in your Arduino software and need to Get the Arduino hex file from it.
• The running form of the above simulation is shown in the figure below.

• You need to run the Proteus simulation after uploading .hex file in Arduino.
• Now if you change the state of the logic state from 0 to 1, the green LED will be turned ON which shows that the circuit is properly working.
• At the same time motor will start rotating in either direction.
• That was the brief discussion about IRF540 Proteus simulation.
