IRLR9343TR

UMW · MOSFETs · TO-252

IRLR9343TR 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 terminal; the datasheet rates gate-to-source voltage VGS at ±20 V.
2 D passive DRAIN terminal; continuous drain current is rated at -20 A (TC=25°C) with VDS of -55 V.
3 S passive SOURCE terminal; the body-diode continuous source current is rated at -20 A.
