Introduction: How to Use MOSFET As a Switch

In this instructable i am going to show how you can use mosfet as a switch

basically it has two uses

1 - as a switch

2 - as an amplifier

A COMPLETE EXPLANATION IS GIVING IN THE VIDEO AS WELL


Step 1: Selecting MOSFET

Here iam using power mosfet ir540

you can use any low power mosfet depend on the condition like 2n7000 etc

Step 2: Circuit Diagram

Impliment the above circuit on breadboard or etc

for login state you have give 5 volt signal at gate to turn on / off this can be done via voltage divider circuit with a help of a switch .....

OR

give a pwm signal from arduino / microcntroller etc to switching the mosfet,

Step 3:

will try this ? when I require a switch like this.

actually the real application of this switch is controlling high voltages
with just a 5 volt logic
according to their datasheet
vdd goes up to 100volt
