CAD (KiCad official)

  • Symbol: H12VHD3U
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: h12vhd3u-etched.step / h12vhd3u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h12vhd3u.step / h12vhd3u.glb are the bare package body.
