CAD (KiCad official)

  • Symbol: MSESD3Z5.0C
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: msesd3z5-0c-etched.step / msesd3z5-0c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); msesd3z5-0c.step / msesd3z5-0c.glb are the bare package body.
