STB80NF55L-06T4

STB80NF55L-06T4 Description

The STB80NF55L-06T4 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power management applications. Part of the STripFET™ II series, it features a 55V drain-to-source voltage (Vdss) and a continuous drain current (Id) of 80A at 25°C (case temperature). With an ultra-low on-resistance (Rds(on)) of just 6.5mΩ at 10V gate drive, this MOSFET minimizes conduction losses, enhancing efficiency in high-current circuits. Packaged in a D2PAK (TO-263) surface-mount format, it is optimized for automotive, industrial, and power supply applications requiring robust thermal performance and reliability.

STB80NF55L-06T4 Features
