CAD (KiCad official)

  • Symbol: SMCJ54A-E3
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB(SMCJ) (KiCad packages3D, STEP)
  • 3D model files: smcj54a-e3-etched.step / smcj54a-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj54a-e3.step / smcj54a-e3.glb are the bare package body.
