IRF630 N-Channel Power MOSFET Transistor

IRF630 is a third-generation power MOSFET specially designed for applications which required high-speed switching. This component is a great combination of low on-state resistance, cost-effective, and rugged design.

IRF630 is designed to sustain load voltage up to 200 V and 9 A current. It can drive current up to 36 A in pulse mode for 300 μs with a duty cycle of 2%. This Power MOSFET is specially designed to minimize input capacitance and gate change, and available in package TO-220.

IRF630 MOSFET Working with Simulation

A MOSFET can be turned ON by supplying proper gate voltage between the gate and source terminal. If the gate voltage is not applied properly, the MOSFET will remain turn OFF condition. For example, we take IRF630 as MOSFET and use this MOSFET as a switching device to turn ON and OFF a LED. The simulation is done in proteus.

Condition-1: When the applied gate voltage is more than 4 V, the LED will turn ON. Here, we apply 5 V between gate and source.

Condition-2: When the applied gate voltage is less than 4 V, the LED remains in OFF condition. In this example, the applied gate voltage is 3V, and the LED seems in OFF condition in the figure below.
