AOD4189

UMW · MOSFETs · TO-252

AOD4189 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 -40 V P-channel MOSFET; the datasheet rates the gate-source voltage at VGS = ±20 V.
2	D	passive	DRAIN of the -40 V P-channel MOSFET, rated VDS = -40 V, with continuous drain current ID = -40 A at VGS = -10 V per the features list.
3	S	passive	SOURCE of the MOSFET; the datasheet gives no separate source-pin rating, and the VDS = -40 V and VGS = ±20 V limits are referenced to this terminal.
