KSMAJ180A-E3

Public Made by Adom

by adom

KUU ESD And Surge Protection (TVS/ESD), SMA. 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: KSMAJ180A-E3
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: ksmaj180a-e3-etched.step / ksmaj180a-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ksmaj180a-e3.step / ksmaj180a-e3.glb are the bare package body.

Provenance

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