WST02N30 from Winsok Semicon, in a SOT-23. 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; the datasheet gives a gate-source limit of ±20 V, a threshold of 2.0 to 4.0 V (VDS=VGS, ID=250uA) and gate leakage of ±100 nA max at VGS=±20V. |
| 2 | S | passive | Source; the body diode carries a continuous source current of 2.0 A max and a pulsed source current of 12 A max. |
| 3 | D | passive | Drain; the drain-source voltage is rated at 300 V and the continuous drain current at 2.0 A (Tc=25℃). |
