PDF datasheet for the IRFP450, a high-voltage N-channel MOSFET in a TO-247 package. The name holds only the part number, so take the exact ratings from the document itself. The part is widely used in off-line switch-mode supplies, PFC stages, inverters and induction heating boards. A technician checks the sheet for drain-source voltage, on-resistance, gate threshold, safe operating area and pinout before choosing a substitute such as a higher-current type. After a short circuit, test the gate drive and current-sense parts before powering up.
