IRFR4105TR

UMW · MOSFETs · TO-252

IRFR4105TR from UMW, in a TO-252. 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 G input GATE of the MOSFET; gate-to-source voltage is rated VGS = ±20 V in the absolute maximum ratings.
2 D passive DRAIN of the MOSFET; the datasheet rates VDS at 55 V and continuous drain current ID at 27 A (VGS = 10 V, TC = 25°C).
3 S passive SOURCE of the MOSFET; it is the reference terminal for the VGS rating and the body-diode ratings (IS, ISM, VSD).
