BZT52B39

Public Made by Adom

by adom

POPPULA Zener Diodes, SOD-123. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

CAD (KiCad official)

  • Symbol: BZT52B39
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52b39-etched.step / bzt52b39-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52b39.step / bzt52b39.glb are the bare package body.
