STW6N90K5

STMicroelectronics · MOSFETs · TO-247

STW6N90K5 from STMicroelectronics, in a TO-247. 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 terminal of the MDmesh K5 N-channel power MOSFET, which the datasheet states is Zener-protected.
2 D passive Drain terminal, also connected to the TAB, for the 900 V N-channel MOSFET rated at VDS 900 V.
3 S passive Source terminal of the N-channel MOSFET, carrying a continuous drain current of 6 A at TC = 25 °C.
