WSK78P10 from Winsok Semicon, in a TO-263-2L. 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; drives the P-channel MOSFET, rated ±20V gate-source, with RDS(ON) specified at VGS=-10V and -4.5V. |
| 2 | D | passive | Drain, connected to the exposed tab; rated -100V drain-source and -78A continuous at TC=25°C. |
| 3 | S | passive | Source; continuous source current up to -80A through the body diode. |
