CAD (KiCad official)

  • Symbol: DSR1K
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: dsr1k-etched.step / dsr1k-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dsr1k.step / dsr1k.glb are the bare package body.
