CAD (KiCad official)

  • Symbol: PESD3.3V52D-C
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: pesd3-3v52d-c-etched.step / pesd3-3v52d-c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd3-3v52d-c.step / pesd3-3v52d-c.glb are the bare package body.

Provenance
