STB11NK50ZT4

STMicroelectronics · MOSFETs · D2PAK

STB11NK50ZT4 from STMicroelectronics, in a D2PAK. 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 Gate input Gate control terminal; gate-source voltage maximum ±30V with integrated back-to-back Zener diodes for ESD protection; gate threshold voltage 3.0-4.5V.
2 Drain passive Drain conduction terminal rated for 500V maximum drain-source voltage with continuous current rating 10A at Tj=25°C and 6.3A at Tj=100°C; includes parasitic body diode.
3 Source passive Source return terminal serving as reference for gate-source and drain-source voltage measurements; carries drain current return path.
