WILLSEMI Will Semicon · MOSFETs · SOT-723
WPM2031-3 from WILLSEMI Will Semicon, in a SOT-723. 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 MOSFET; the datasheet gives a gate-source voltage rating of ±5 V (VGS). |
| 2 | S | passive | Source of the P-channel MOSFET; the datasheet rates the device for a drain-source voltage of -20 V (VDS). |
| 3 | D | passive | Drain of the P-channel MOSFET; continuous drain current is -0.65 A at TA=25°C (steady state, 1 in² pad) and pulsed drain current is -1.0 A. |
