STP5NK50Z

STMicroelectronics · MOSFETs · TO-220

STP5NK50Z from STMicroelectronics, in a TO-220. 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 of the Zener-protected N-channel MOSFET; gate-source voltage is limited to ±30 V (absolute maximum, Table 1).
2 D passive Drain of the MOSFET, also connected to the mounting tab; drain-source voltage is 500 V and continuous drain current is 4.4 A at TC = 25 °C (Table 1).
3 S passive Source of the MOSFET; source-drain diode forward current is rated 4.4 A continuous and 17.6 A pulsed (Table 7).
