AOD4185-ES from ElecSuper, 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 | Gate | input | Gate terminal of the P-channel MOSFET; the datasheet rates the gate-source voltage VGS at ±25 V. |
| 2 | Drain | passive | Drain terminal of the P-channel MOSFET; the datasheet rates the drain-source voltage BVDSS at -40 V and the continuous drain current ID at -45 A at TC=25°C. |
| 3 | Source | passive | Source terminal of the P-channel MOSFET; the datasheet gives its electrical characteristics with respect to VGS=0V and VDS, with the drain-source voltage rated at -40 V. |
