**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.
