CAD (KiCad official)

  • Symbol: MSESD5Z5.0C
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: msesd5z5-0c-etched.step / msesd5z5-0c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); msesd5z5-0c.step / msesd5z5-0c.glb are the bare package body.
