CAD (KiCad official)

  • Symbol: KESD5471X
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: kesd5471x-etched.step / kesd5471x-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kesd5471x.step / kesd5471x.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
