STW7N105K5

STMicroelectronics · MOSFETs · TO-247-3

STW7N105K5 from STMicroelectronics, in a TO-247-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate control terminal rated for ±30 V gate-source voltage; gate threshold voltage VGS(th) = 3-5 V for MOSFET switching control.
2 D passive Drain terminal for main switching current with drain-source breakdown voltage V(BR)DSS = 1050 V; rated for 4 A continuous current at 25°C and 3 A at 100°C; 16 A pulsed.
3 S passive Source reference terminal serving as return path for drain current and gate-source voltage reference point.

CAD (KiCad official)

  • Symbol: STW7N105K5
  • Footprint: Package_TO_SOT_THT:TO-247-3_Vertical
  • 3D model: TO-247-3 (KiCad packages3D, STEP)
  • 3D model files: stw7n105k5-etched.step / stw7n105k5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stw7n105k5.step / stw7n105k5.glb are the bare package body.
