CAD (KiCad official)

  • Symbol: PTUC05D5B
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: ptuc05d5b-etched.step / ptuc05d5b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ptuc05d5b.step / ptuc05d5b.glb are the bare package body.
