SMFJ150A

Public Made by Adom

by adom

BORN ESD And Surge Protection (TVS/ESD), SOD-123F. 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: SMFJ150A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: smfj150a-etched.step / smfj150a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smfj150a.step / smfj150a.glb are the bare package body.
