CAD (KiCad official)

  • Symbol: BAT54WSX
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bat54wsx-etched.step / bat54wsx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54wsx.step / bat54wsx.glb are the bare package body.
