CAD (KiCad official)

  • Symbol: BSD3C031V
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bsd3c031v-etched.step / bsd3c031v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsd3c031v.step / bsd3c031v.glb are the bare package body.
