WSF40N10A from Winsok Semicon, 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; gate-source voltage is rated at ±20 V maximum, with a typical threshold of 1.5 V (0.9 to 2.5 V) at ID=250uA. |
| 2 | D | passive | Drain, also connected to the exposed tab; drain-source voltage is rated at 100 V, with continuous current of 31 A at TC=25℃ and pulsed current of 55 A. |
| 3 | S | passive | Source; the body diode carries a continuous source current of 12 A, with forward voltage of 1.3 V max at IS=1A. |
