CAD (KiCad official)

  • Symbol: US8MC
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: us8mc-etched.step / us8mc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us8mc.step / us8mc.glb are the bare package body.
