SMAJ7.0A

Public Made by Adom

by adom

FOSAN ESD And Surge Protection (TVS/ESD), SMA(DO-214AC). 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: SMAJ7.0A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: smaj7-0a-etched.step / smaj7-0a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj7-0a.step / smaj7-0a.glb are the bare package body.

Provenance

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