CAD (KiCad official)

  • Symbol: ST30100C
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220AB (KiCad packages3D, STEP)
  • 3D model files: st30100c-etched.step / st30100c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); st30100c.step / st30100c.glb are the bare package body.
