CAD (KiCad official)

  • Symbol: BZX585-C68
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523(SC-79) (KiCad packages3D, STEP)
  • 3D model files: bzx585-c68-etched.step / bzx585-c68-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx585-c68.step / bzx585-c68.glb are the bare package body.
