CAD (KiCad official)

  • Symbol: SM6F22AY
  • Footprint: Diode_SMD:D_SOD-128
  • 3D model: SOD-128 (KiCad packages3D, STEP)
  • 3D model files: sm6f22ay-etched.step / sm6f22ay-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm6f22ay.step / sm6f22ay.glb are the bare package body.
