BAT54WS

FUXINSEMI · Schottky Diodes · SOD-323(SC-90)

BAT54WS from FUXINSEMI, in a SOD-323(SC-90). 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 K passive Cathode (marked with the band on the package, negative terminal); the datasheet gives DC blocking voltage VR of 21 V and non-repetitive peak reverse voltage VRM of 30 V.
2 A passive Anode (positive terminal); the datasheet gives forward continuous current IF of 200 mA and average rectified output current IO of 100 mA.

CAD (KiCad official)

  • Symbol: BAT54WS
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323(SC-90) (KiCad packages3D, STEP)
  • 3D model files: bat54ws-etched.step / bat54ws-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54ws.step / bat54ws.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: FUXINSEMI datasheet (3 pp, sha256 d1454cfb4564841d, retrieved 2026-10-12, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
