CAD (KiCad official)

  • Symbol: SMCJ64A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smcj64a-etched.step / smcj64a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj64a.step / smcj64a.glb are the bare package body.
