CAD (KiCad official)

  • Symbol: CJSMF33CA
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123FL (KiCad packages3D, STEP)
  • 3D model files: cjsmf33ca-etched.step / cjsmf33ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cjsmf33ca.step / cjsmf33ca.glb are the bare package body.
