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. |
