CAD (KiCad official)

  • Symbol: SESD3Z5C
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sesd3z5c-etched.step / sesd3z5c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sesd3z5c.step / sesd3z5c.glb are the bare package body.
