CAD (KiCad official)

  • Symbol: D3Z3V9BF-7
  • Footprint: Diode_SMD:D_SOD-323F
  • 3D model: SOD-323F (KiCad packages3D, STEP)
  • 3D model files: d3z3v9bf-7-etched.step / d3z3v9bf-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); d3z3v9bf-7.step / d3z3v9bf-7.glb are the bare package body.
