CAD (KiCad official)

  • Symbol: AD-BZT52C43
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: ad-bzt52c43-etched.step / ad-bzt52c43-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad-bzt52c43.step / ad-bzt52c43.glb are the bare package body.
