CAD (KiCad official)

  • Symbol: PESD5V0S1UB-MS
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: pesd5v0s1ub-ms-etched.step / pesd5v0s1ub-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd5v0s1ub-ms.step / pesd5v0s1ub-ms.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
