CAD (KiCad official)

  • Symbol: DSF1G E1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: dsf1g-e1g-etched.step / dsf1g-e1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dsf1g-e1g.step / dsf1g-e1g.glb are the bare package body.
