The IRFP460 MOSFET is an N-channel MOSFET. It is rated for a drain-source breakdown voltage of 500V and a continuous drain current of 20A. This MOSFET is a third-generation device designed with fast switching and low on-resistance in mind. Specifically, it has a maximum drain-source on-state resistance of 0.27 Ohms.
Basically this IRFP460 MOSFET is suitable for switching applications at high voltages making it ideal for use in switch mode power supplies, DC-to-DC converters, motor drivers, inverters, and other power conversion applications.
It can handle up to 80A pulses and can dissipate 280W of power if adequate cooling is provided.

Questions & Answers
good day sir.
I building my final year project on a topic Design and construction of microcontroller-based hybrid surge suppression Device combining TVS DIODES AND FET-BASED SWITCH ARCHITECTURE and I use MOSFETs as switch on AC mains but I find it difficult to drive the MOSFETS using Transistor as gate driver
Hey Godfrey, driving MOSFETs directly on AC mains using only a transistor is not easy because the source voltage keeps changing with the AC waveform. Normally an isolated gate driver or a high-side gate driver IC is used for this job. If you can share your circuit diagram or the MOSFET part number, then I can suggest a suitable gate drive method.
