CAD (KiCad official)

  • Symbol: CGRKM4001-HF
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: cgrkm4001-hf-etched.step / cgrkm4001-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cgrkm4001-hf.step / cgrkm4001-hf.glb are the bare package body.
