CAD (KiCad official)

  • Symbol: MM3Z3V3BW
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: mm3z3v3bw-etched.step / mm3z3v3bw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm3z3v3bw.step / mm3z3v3bw.glb are the bare package body.
