CAD (KiCad official)

  • Symbol: 1SS427
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: 1ss427-etched.step / 1ss427-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1ss427.step / 1ss427.glb are the bare package body.
