WPM2031-3

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.

Manufacturer WILLSEMI Will Semicon
Package SOT-723
Category Transistors/Thyristors
Pins 3

CAD (KiCad official)

  • Symbol: WPM2031-3
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: wpm2031-3-etched.step / wpm2031-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wpm2031-3.step / wpm2031-3.glb are the bare package body.
