CAD (KiCad official)

  • Symbol: MM3Z2V0
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: mm3z2v0-etched.step / mm3z2v0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm3z2v0.step / mm3z2v0.glb are the bare package body.
