BAT54W S1

CBI · Schottky Diodes · SOD-123

BAT54W S1 from CBI, in a SOD-123. 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 Cathode passive Cathode of the Schottky barrier diode; the datasheet rates the device for a 30 V reverse voltage and 200 mA forward current.
2 Anode passive Anode of the Schottky barrier diode; the datasheet rates the device for a 30 V reverse voltage and 200 mA forward current.

CAD (KiCad official)

  • Symbol: BAT54W S1
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bat54w-s1-etched.step / bat54w-s1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54w-s1.step / bat54w-s1.glb are the bare package body.
