CAD (KiCad official)

  • Symbol: MS05A40LD
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2L (KiCad packages3D, STEP)
  • 3D model files: ms05a40ld-etched.step / ms05a40ld-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ms05a40ld.step / ms05a40ld.glb are the bare package body.
