STD7NK40ZT4 Description

Short technical summary and product information.

The STD7NK40ZT4 is an N-Channel power MOSFET from STMicroelectronics designed for high-voltage switching applications. It features a maximum drain-to-source voltage of 400V and a continuous drain current of 5.4A at case temperature Tc. The device offers a maximum on-resistance of 1 Ohm at 2.7A and 10V gate drive, enabling efficient power conversion.

 

With a maximum power dissipation of 70W and an operating junction temperature range of -55°C to 150°C, this MOSFET is suitable for demanding environments. The gate threshold voltage is 4.5V at 50µA, and the maximum gate-source voltage is ±30V. The device is housed in a TO-252-3 (DPak) surface-mount package, making it compatible with automated assembly processes.
