SMCJ28CA-E3

Public Made by Adom

by adom

Vishay Intertech TVS, SMC(DO-214AB). 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: SMCJ28CA-E3
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smcj28ca-e3-etched.step / smcj28ca-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj28ca-e3.step / smcj28ca-e3.glb are the bare package body.
