CAD (KiCad official)

  • Symbol: MST52L40BTS
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: mst52l40bts-etched.step / mst52l40bts-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mst52l40bts.step / mst52l40bts.glb are the bare package body.
