CAD (KiCad official)

  • Symbol: MM5Z9V1
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: mm5z9v1-etched.step / mm5z9v1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm5z9v1.step / mm5z9v1.glb are the bare package body.
