CAD (KiCad official)

  • Symbol: US1A-13-F
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: us1a-13-f-etched.step / us1a-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us1a-13-f.step / us1a-13-f.glb are the bare package body.
