CAD (KiCad official)

  • Symbol: SL493TA
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: sl493ta-etched.step / sl493ta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl493ta.step / sl493ta.glb are the bare package body.
