CAD (KiCad official)

  • Symbol: BV_ESD523-33C
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: bv-esd523-33c-etched.step / bv-esd523-33c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bv-esd523-33c.step / bv-esd523-33c.glb are the bare package body.
