CAD (KiCad official)

  • Symbol: ESD3Z12V0
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esd3z12v0-etched.step / esd3z12v0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd3z12v0.step / esd3z12v0.glb are the bare package body.
