CAD (KiCad official)

  • Symbol: PESDR0541P1A
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: pesdr0541p1a-etched.step / pesdr0541p1a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesdr0541p1a.step / pesdr0541p1a.glb are the bare package body.
