CAD (KiCad official)

  • Symbol: ESD0501BU
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: esd0501bu-etched.step / esd0501bu-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd0501bu.step / esd0501bu.glb are the bare package body.
