NCV8440STCT1G

Overview

The NCV8440STCT1G is a 2.6A, 52V N-channel logic-level clamped MOSFET designed for automotive and industrial applications. It features integrated ESD protection rated at 5000V (Human Model) and active overvoltage gate-to-drain clamping to enhance stability under transient conditions. The device includes an internal series gate resistor to optimize switching performance and handles high energy loads typical of inductive applications. Key electrical ratings include a maximum drain-source voltage of 52V to 59V, a continuous drain current of 2.6A, and a single-pulse drain current of 10A. It operates within a temperature range of -55°C to 150°C and dissipates up to 1.69W of power.
