CAD (KiCad official)

  • Symbol: BSD3A031LV45
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bsd3a031lv45-etched.step / bsd3a031lv45-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsd3a031lv45.step / bsd3a031lv45.glb are the bare package body.
