IRF730

OSEN · MOSFETs · TO-220AB

IRF730 from OSEN, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Gate input Gate control input; gate-source voltage is rated ±30 V continuous with a 2.0 V to 4.0 V threshold at ID=250µA.
2 Drain passive Drain terminal, rated 450 V drain-source voltage and 6 A continuous drain current (25 A pulsed).
3 Source passive Source terminal of the N-channel MOSFET, with a 6 A continuous body-diode forward current.
