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. |
