CAD (KiCad official)

  • Symbol: SMCJ70A-E3
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smcj70a-e3-etched.step / smcj70a-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smcj70a-e3.step / smcj70a-e3.glb are the bare package body.
