CAD (KiCad official)

  • Symbol: ESD5651N
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: esd5651n-etched.step / esd5651n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5651n.step / esd5651n.glb are the bare package body.
