WNM4002-3

WILLSEMI Will Semicon · MOSFETs · SOT-523

WNM4002-3 from WILLSEMI Will Semicon, in a SOT-523. 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 N-channel MOSFET; the datasheet gives a maximum gate-to-source voltage rating of 6.0 V (VGSS).
2 S passive Source of the N-channel MOSFET; the datasheet gives no separate pin-level limit, and the device is rated at 20 V drain-to-source (VDSS) with 0.3 A continuous drain current.
3 D passive Drain of the N-channel MOSFET; the device is rated for 20 V drain-to-source (VDSS), 0.3 A continuous drain current and 0.6 A pulsed drain current (t<300 µs, duty <2%).

CAD (KiCad official)

  • Symbol: WNM4002-3
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 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: wnm4002-3-etched.step / wnm4002-3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wnm4002-3.step / wnm4002-3.glb are the bare package body.
