CAD (KiCad official)

  • Symbol: DSEI60-10A
  • Footprint: Package_TO_SOT_THT:TO-247-2_Vertical
  • 3D model: TO-247-2 (KiCad packages3D, STEP)
  • 3D model files: dsei60-10a-etched.step / dsei60-10a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dsei60-10a.step / dsei60-10a.glb are the bare package body.
