WM03P42M from Wayon, 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; gate-source voltage limited to ±12 V, with threshold VGS(th) of -0.7 V min, -1 V typ and -1.3 V max at ID = -250µA. |
| 2 | S | passive | Source; drain-source diode continuous source current IS is -4.2 A max, with VSD of -1.2 V max at IS = -4.2A. |
| 3 | D | passive | Drain; VDS rated -30 V, continuous drain current -4.2 A at TA=25°C, pulsed -16 A. |
