BC2302W

CBI · MOSFETs · SOT-323

BC2302W from CBI, in a SOT-323. 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 terminal; gate-source voltage limited to ±8 V with threshold of 0.60 V min to 1.2 V max at ID=250µA.
2 SOURCE passive Source terminal; continuous source-drain diode current is 0.6 A.
3 DRAIN passive Drain terminal; drain-source voltage is 20 V max with continuous drain current of 2.1 A.

CAD (KiCad official)

  • Symbol: BC2302W
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: bc2302w-etched.step / bc2302w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc2302w.step / bc2302w.glb are the bare package body.
