CAD (KiCad official)

  • Symbol: STS321033U202
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: sts321033u202-etched.step / sts321033u202-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sts321033u202.step / sts321033u202.glb are the bare package body.
