CAD (KiCad official)

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

Provenance
