ESD3V3L1BA-MS

Public Made by Adom

by adom

MSKSEMI 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: ESD3V3L1BA-MS
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: esd3v3l1ba-ms-etched.step / esd3v3l1ba-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd3v3l1ba-ms.step / esd3v3l1ba-ms.glb are the bare package body.
