CAD (KiCad official)

  • Symbol: ESD18VD3
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esd18vd3-etched.step / esd18vd3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd18vd3.step / esd18vd3.glb are the bare package body.
