CAD (KiCad official)

  • Symbol: KESD9B5VD-2
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: kesd9b5vd-2-etched.step / kesd9b5vd-2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kesd9b5vd-2.step / kesd9b5vd-2.glb are the bare package body.
