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. |
