CAD (KiCad official)

  • Symbol: BZX384-B56
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323(SC-76) (KiCad packages3D, STEP)
  • 3D model files: bzx384-b56-etched.step / bzx384-b56-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx384-b56.step / bzx384-b56.glb are the bare package body.
