CAD (KiCad official)

  • Symbol: BZT52B9V1
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52b9v1-etched.step / bzt52b9v1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52b9v1.step / bzt52b9v1.glb are the bare package body.
