CAD (KiCad official)

  • Symbol: STP8N120K5
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: stp8n120k5-etched.step / stp8n120k5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stp8n120k5.step / stp8n120k5.glb are the bare package body.
