CAD (KiCad official)

  • Symbol: AD-BZT52C27S
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: ad-bzt52c27s-etched.step / ad-bzt52c27s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ad-bzt52c27s.step / ad-bzt52c27s.glb are the bare package body.

Provenance

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