CAD (KiCad official)

  • Symbol: CUHZ20V
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: cuhz20v-etched.step / cuhz20v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cuhz20v.step / cuhz20v.glb are the bare package body.
