CAD (KiCad official)

  • Symbol: DST857BDJ-7
  • Footprint: Package_TO_SOT_SMD:SOT-963
  • 3D model: SOT-963 (KiCad packages3D, STEP)
  • 3D model files: dst857bdj-7-etched.step / dst857bdj-7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); dst857bdj-7.step / dst857bdj-7.glb are the bare package body.
