CAD (KiCad official)

  • Symbol: SMDJ20CA
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: smdj20ca-etched.step / smdj20ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smdj20ca.step / smdj20ca.glb are the bare package body.
