The 84CNQ040SMS2 is a rectifier array that is designed to be used in advanced high-speed switching applications. It is designed to feature low forward voltage drop, low power dissipation, and maximum output current ratings, making it an ideal solution for a wide range of applications, including smart phones, tablets, and personal digital assistants (PDAs).

Application Field

The 84CNQ040SMS2 rectifier array is primarily used as an efficient, low power dissipation solution for sink-less power management in high power applications. The rectifier array offers excellent thermal resistance from junction to ambient temperature, allowing it to tolerate transient over-currents without disruption. As such, it can be used in applications such as LED lighting, automotive battery chargers, bridge rectification, and DC/DC converters.

In addition, the rectifier array’s small footprint makes it an ideal solution for high density applications, such as smart phones, tablets, and PDAs, where space is limited. It is designed specifically to meet the stringent requirements of such high-speed, high-efficiency applications.

Working Principle

The 84CNQ040SMS2 rectifier array works by converting AC power into DC power. It features four schottky diodes in a small package, with each diode providing a low forward voltage drop and low power dissipation. The diodes are connected in a synchronous rectification configuration, which allows for fast and easy switching during power conversion. As a result, it is able to provide high efficiency, low power consumption, and low cost.

The rectifier array operates in an open-loop configuration to ensure that the current flow is not affected by external factors. It utilizes a flat surface mount (FSM) package to ensure efficient heat dissipation, and is rated to operate at up to 85°C junction temperature. In addition, its maximum reverse leakage current depends on the forward current, and as such can be used in applications where high reverse current is necessary.

The 84CNQ040SMS2 is a reliable and efficient rectifier array, providing high-speed switching capabilities with maximum output current ratings, low forward voltage drop, and low power dissipation. Its small footprint and thermal resistance make it the ideal solution for high power, high-speed, high-efficiency applications such as LED lighting, automotive battery chargers, bridge rectification, and DC/DC converters.
