SMAJ26CAH

Public Made by Adom

by adom

Taiwan Semiconductor ESD And Surge Protection (TVS/ESD), DO-214AC(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: SMAJ26CAH
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: smaj26cah-etched.step / smaj26cah-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj26cah.step / smaj26cah.glb are the bare package body.
