Simulation of IRF9540 P-channel MOSFET

IRF9540 is a P-channel MOSFET. Here, we will simulate IRF9540 available in proteus. The MOSFET is a power electronics switch that will turn ON when the proper voltage is applied to the gate terminal. IRF9540 is a P-channel MOSFET. Hence, we need to apply a proper negative voltage to turn ON MOSFET.

We use a 1K potentiometer to change the value of the applied voltage. DC voltmeter shows a reading of applied gate voltage. Once, the gate voltage is more than the threshold voltage between drain and source, the MOSFET will turn ON. And the current will pass through the circuit.

A battery and LED are connected in the path of drain-to-source. When the MOSFET is turned ON, the LED will glow.
