CAD (KiCad official)

  • Symbol: BSD9C051V
  • Footprint: Diode_SMD:D_SOD-923
  • 3D model: SOD-923 (KiCad packages3D, STEP)
  • 3D model files: bsd9c051v-etched.step / bsd9c051v-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bsd9c051v.step / bsd9c051v.glb are the bare package body.
