IRF1405 MOSFET Working with Simulation

Let’s make a switching circuit with the help of IRF1405. This device is an N-channel MOSFET and it is a voltage control device. It means, if the gate-to-source voltage is sufficiently available, the device will turn ON. And if a gate-to-source voltage is not available, the device will remain turn OFF condition.  To simulate this, we will make a simple example circuit for IRD1405 in Proteus as shown below

IRF1405 Circuit Diagram

Condition-1 Gate-to-Source voltage VDS = 5V

In this condition, when we turn ON the switch, the current will pass through the load and LED. Once MOSFET is turned ON, it will remain ON until the gate voltage is 0 V.

Condition-2 Gate-to-Source voltage VDS = 5V

In this condition, gate-to-source is zero. Hence, the MOSFET remains in OFF condition and the current will not pass through load and LED.
