WSF4N65 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; controls the channel, with VGS rated at ±30 V maximum, VGS(th) 2.0 to 4.0 V and IGSS of ±100 nA maximum at VGS=±30 V. |
| 2 | D | passive | Drain, also the exposed tab; rated for VDS of 650 V and continuous ID of 4 A at TC=25℃ (16 A pulsed). |
| 3 | S | passive | Source; the body diode runs from source to drain, with continuous source current IS of 4 A maximum and VSD of 1.4 V maximum. |
