STB11NK40ZT4 Description

Short technical summary and product information.

The STB11NK40ZT4 is an N-Channel MOSFET from STMicroelectronics designed for high-voltage switching applications. It features a maximum drain-source voltage of 400V and a continuous drain current rating of 9A at case temperature. The device offers a low on-resistance of 550mOhm (maximum) at 4.5A drain current with 10V gate drive, ensuring efficient power conversion.

 

Key electrical characteristics include a typical gate threshold voltage of 4.5V at 100µA drain current, a total gate charge of 32nC at 10V, and input capacitance of 930pF at 25V drain-source bias. The MOSFET can dissipate up to 110W of power and operates across a junction temperature range of -55°C to 150°C, making it suitable for demanding thermal environments.

 

The part is supplied in a surface-mount D2PAK package (TO-263-3, D²Pak with 2 leads and tab), which is designed for efficient heat transfer and compact PCB layouts. This package is widely used in power supply, motor control, and DC-DC converter designs where board space is limited.
