CAD (KiCad official)

  • Symbol: MM3Z8V2T1G
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: mm3z8v2t1g-etched.step / mm3z8v2t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mm3z8v2t1g.step / mm3z8v2t1g.glb are the bare package body.
