CAD (KiCad official)

  • Symbol: BZT52-C51_R1_00001
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52-c51-r1-00001-etched.step / bzt52-c51-r1-00001-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52-c51-r1-00001.step / bzt52-c51-r1-00001.glb are the bare package body.
