CAD (KiCad official)

  • Symbol: HESD3B5CM
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: hesd3b5cm-etched.step / hesd3b5cm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hesd3b5cm.step / hesd3b5cm.glb are the bare package body.

Provenance

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