CAD (KiCad official)

  • Symbol: SD03C-MS
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sd03c-ms-etched.step / sd03c-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd03c-ms.step / sd03c-ms.glb are the bare package body.
