WST4045

Winsok Semicon · MOSFETs · SOT-23-3L

WST4045 from Winsok 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; gate-source voltage is rated at ±20 V maximum.
2 S passive Source of the P-channel MOSFET; continuous drain current is rated -4.3 A.
3 D passive Drain; drain-source voltage is rated at -40 V maximum.

CAD (KiCad official)

  • Symbol: WST4045
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: wst4045-etched.step / wst4045-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wst4045.step / wst4045.glb are the bare package body.
