CAD (KiCad official)

  • Symbol: BZT52C5V1S-7-F
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bzt52c5v1s-7-f-etched.step / bzt52c5v1s-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c5v1s-7-f.step / bzt52c5v1s-7-f.glb are the bare package body.
