CAD (KiCad official)

  • Symbol: SMF6.5CA-Q
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: smf6-5ca-q-etched.step / smf6-5ca-q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smf6-5ca-q.step / smf6-5ca-q.glb are the bare package body.
