CAD (KiCad official)

  • Symbol: BZT52C75
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52c75-etched.step / bzt52c75-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c75.step / bzt52c75.glb are the bare package body.
