CAD (KiCad official)

  • Symbol: BZT52C3V0Q
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: bzt52c3v0q-etched.step / bzt52c3v0q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzt52c3v0q.step / bzt52c3v0q.glb are the bare package body.
