STD5NK40ZT4 Description

Short technical summary and product information.

The STD5NK40ZT4 is an N-channel power MOSFET manufactured by STMicroelectronics. It is designed for high-voltage switching applications, featuring a drain-source voltage (Vdss) of 400V and a continuous drain current (Id) of 3A. The device is housed in a DPAK (TO-252) surface-mount package, which offers a compact footprint suitable for automated assembly processes.

 

This MOSFET is part of STMicroelectronics' SuperMESH series, optimized for high efficiency and ruggedness. Key electrical characteristics include a low on-resistance (Rds(on)) that minimizes conduction losses, making it suitable for power management circuits. The device is designed for use in applications such as switch-mode power supplies (SMPS), power factor correction (PFC) circuits, and lighting ballasts.

 

The DPAK package provides excellent thermal performance and is compatible with standard surface-mount soldering processes. The STD5NK40ZT4 is RoHS compliant, ensuring environmental compatibility for modern electronic designs.
