Description
These high-voltage devices are Zener-protected N-channel Power MOSFETs developed using the SuperMESH technology by STMicroelectronics, an optimization of the well-established PowerMESH. In addition to a significant reduction in on- resistance, these devices are designed to ensure a high level of dv/dt capability for the most demanding applications. 1 2 3 TAB TO-220 TAB D PAK2 1 2 TO-220FP D(2, TAB) G(1) S(3) NG1D2TS3Z Product status links STB11NK40ZT4 STP11NK40Z STP11NK40ZFP N-channel 400 V, 0.47 Ω typ., 9 A SuperMESH Power MOSFETs in a D2PAK, TO‑220 and TO‑220FP packages STB11NK40ZT4, STP11NK40Z, STP11NK40ZFP Datasheet DS2843 - Rev 9 - July 2025 For further information, contact your local STMicroelectronics sales office.
