CAD (KiCad official)

  • Symbol: CMHZ4702 TR PBFREE
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: cmhz4702-tr-pbfree-etched.step / cmhz4702-tr-pbfree-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cmhz4702-tr-pbfree.step / cmhz4702-tr-pbfree.glb are the bare package body.
