CAD (KiCad official)

  • Symbol: BZX84J-B15
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: bzx84j-b15-etched.step / bzx84j-b15-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzx84j-b15.step / bzx84j-b15.glb are the bare package body.
