CAD (KiCad official)

  • Symbol: SD12-MS
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sd12-ms-etched.step / sd12-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd12-ms.step / sd12-ms.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
