CAD (KiCad official)

  • Symbol: US1MH
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: us1mh-etched.step / us1mh-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us1mh.step / us1mh.glb are the bare package body.

Provenance

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