CAD (KiCad official)

  • Symbol: LY523DC05
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: ly523dc05-etched.step / ly523dc05-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ly523dc05.step / ly523dc05.glb are the bare package body.
