CESD5V0D3

Public Made by Adom

by adom

UMW ESD And Surge Protection (TVS/ESD), SOD-323. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: CESD5V0D3
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: cesd5v0d3-etched.step / cesd5v0d3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cesd5v0d3.step / cesd5v0d3.glb are the bare package body.

Provenance

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