IRF510 N-channel Power MOSFET

IRF510 is a third-generation Power MOSFET with the best combination of fast switching and low on-state resistance. This component is available at a lower cost. Hence, it is widely used in industrial applications for power dissipation levels up to 43W.

IRF510 MOSFET is capable to withstand drain-to-source voltage V_DS up to 100V and continuous drain current I_D up to 5.6A. It can withstand 20A current in pulse mode and belongs to the package TO-220AB. It is designed for applications that require high-speed switching like a motor driver, switching converter and regulators, etc.

Simulation

This MOSFET is a switching device that will turn on when sufficient gate voltage is available or else, it will remain in turn-off condition. In this simulation, we will use IRF510 to turn on an LED. If the applied gate voltage is not sufficient to turn on the device, the current will not pass from drain to source and the LED will remain in off condition.

When the gate voltage is sufficient to turn on MOSFET, the LED will turn on and the current will pass through the drain to the source.
