Datasheet for the IRFP460, a high-voltage N-channel power MOSFET in a TO-247 package, supplied as a PDF. No ratings appear in the file name, so read the voltage and current limits from the document. This MOSFET is common in switch-mode supplies, induction heaters, inverters and audio power stages. Technicians use the sheet to compare on-resistance, gate charge, capacitance and pinout when looking for a replacement or cross-reference. Counterfeit parts of this type are widespread, so test a new device before fitting it. Opens in any PDF reader.
