# WPM2026-3

**WILLSEMI Will Semicon** · MOSFETs · SOT-23

WPM2026-3 from WILLSEMI Will 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 of the P-channel enhancement MOSFET; the gate-source voltage limit is printed as ±V in the absolute maximum table, with the numeric value not legible in the extracted text. |
| 2 | S | passive | Source of the P-channel MOSFET, the reference terminal for VGS (VDS rated at -20 V). |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for VDS = -20 V and continuous drain current ID of -3.2 A at TA = 25°C. |

## CAD (KiCad official)

- Symbol: `WPM2026-3`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `wpm2026-3-etched.step` / `wpm2026-3-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `wpm2026-3.step` / `wpm2026-3.glb` are the bare package body.
