CAD (KiCad official)

  • Symbol: B5817W-MS
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: b5817w-ms-etched.step / b5817w-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b5817w-ms.step / b5817w-ms.glb are the bare package body.
