BAS20W

ST Semtech · Switching Diodes · SOT-323

BAS20W from ST Semtech, 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 A passive Anode of the single diode (BAS19W/BAS20W/BAS21W share this pinout); BAS20W is rated for 200 V reverse voltage and 200 mA continuous forward current.
2 NC unconnected Not connected internally on the single-diode BAS20W; no diode terminal is drawn at pin 2 in the package diagram.
3 K passive Cathode of the single diode; BAS20W reverse breakdown is 200 V minimum at IR = 100 µA.

  • Symbol: BAS20W
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: bas20w-etched.step / bas20w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas20w.step / bas20w.glb are the bare package body.
