IRFZ46N

OSEN · MOSFETs · TO-220

IRFZ46N from OSEN, in a TO-220. 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 ±20 V continuous, with threshold of 2.0 V min to 4.0 V max at ID=250µA.
2 Drain passive Drain terminal; drain-source voltage is rated 60 V with 55 A continuous drain current and 220 A pulsed.
3 Source passive Source terminal; continuous drain-source diode forward current is 55 A max.
