CAD (KiCad official)

  • Symbol: MM1Z2V4B
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mm1z2v4b-etched.step / mm1z2v4b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm1z2v4b.step / mm1z2v4b.glb are the bare package body.
