WSG02N20 from Winsok Semicon, in a SOT-223. 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 ±20 V absolute maximum, with a typical threshold of 2.8 V (2.0 to 4.0 V) at ID=250uA. |
| 2 | D | passive | Drain; drain-source voltage is rated 200 V maximum, with continuous drain current of 2.0 A at Tc=25℃ and pulsed drain current of 10 A. |
| 3 | S | passive | Source; continuous source (body diode) current is 2 A maximum and pulsed source current is 10 A maximum. |
