CAD (KiCad official)

  • Symbol: BZT52B16
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52b16-etched.step / bzt52b16-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52b16.step / bzt52b16.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
