ESD9D3V3C

Public Made by Adom

by adom

Leiditech TVS, SOD-923. 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: ESD9D3V3C
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: esd9d3v3c-etched.step / esd9d3v3c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd9d3v3c.step / esd9d3v3c.glb are the bare package body.

Provenance

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