WPM3401-3 from WILLSEMI Will Semicon, in a SOT-23-3L. 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 of the P-channel enhancement-mode MOSFET; gate-source voltage is rated ±12 V (absolute maximum). |
| 2 | S | passive | Source terminal of the MOSFET; the body diode forward voltage is -0.75 V typical and -1.5 V maximum at IS = -1.0 A, VGS = 0 V. |
| 3 | D | passive | Drain terminal of the MOSFET; drain-source voltage is -30 V, with continuous drain current of -4.6 A at TA = 25°C (steady state, 1 in² pad). |
