CAD (KiCad official)

  • Symbol: HCPDH3V3UB-HF
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: hcpdh3v3ub-hf-etched.step / hcpdh3v3ub-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hcpdh3v3ub-hf.step / hcpdh3v3ub-hf.glb are the bare package body.
