CAD (KiCad official)

  • Symbol: BZT52C15T-7
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: bzt52c15t-7-etched.step / bzt52c15t-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c15t-7.step / bzt52c15t-7.glb are the bare package body.
