WST6003

Winsok Semicon · MOSFETs · SOT-523

WST6003 from Winsok 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 Gate input Gate of the P-channel MOSFET; gate-source voltage is rated ±6 V and the gate-source terminals are ESD protected to 2000 V.
2 Source passive Source terminal of the P-channel MOSFET; the datasheet gives no separate pin-level limit, so the device limits apply (VDS -20 V, ID -0.35 A at TC=25℃).
3 Drain passive Drain terminal of the P-channel MOSFET; drain-source voltage is rated -20 V and continuous drain current is -0.35 A at TC=25℃ (VGS = -4.5 V).

CAD (KiCad official)

  • Symbol: WST6003
  • 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: wst6003-etched.step / wst6003-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); wst6003.step / wst6003.glb are the bare package body.
