CAD (KiCad official)

  • Symbol: MMSZ4680
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mmsz4680-etched.step / mmsz4680-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmsz4680.step / mmsz4680.glb are the bare package body.

Provenance

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