CAD (KiCad official)

  • Symbol: B5817WS
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323(SC-90) (KiCad packages3D, STEP)
  • 3D model files: b5817ws-etched.step / b5817ws-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b5817ws.step / b5817ws.glb are the bare package body.
