CAD (KiCad official)

  • Symbol: SMF4747A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: smf4747a-etched.step / smf4747a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf4747a.step / smf4747a.glb are the bare package body.
