CAD (KiCad official)

  • Symbol: PESDU0521P1
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: pesdu0521p1-etched.step / pesdu0521p1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesdu0521p1.step / pesdu0521p1.glb are the bare package body.
