The 444CNQ035 rectifier array is a semiconductor device that is designed to control electric current in a circuit. It is used in distributed power supply systems, switching and switching regulators, high current dc-dc converters, and in voltage converters. This device is a four-terminal active rectifier that uses a pair of Schottky diodes and a high-speed Emitter-Followed-Driver (EFD) transistor output. The device offers low voltage drop, low power dissipation, low leakage current, and a fast reverse recovery time. The result is an efficient and compact electrically isolated package with superior energy efficiency.

The 444CNQ035 rectifier array features four terminals that are configured as an antithetic pair, meaning each of the two pairs has opposite polarities. With this configuration, the device can quickly switch between positive and negative voltages. Each pair is also formed using a pair of Schottky diodes, giving the device low conduction voltage drops in both directions. This feature helps to reduce power dissipation and increase efficiency.

The input voltage, normally 12Vdc, is fed into the base of the EFD transistor. This voltage is then rectified by the two Schottky diodes. The internal resistance of the EFD transistor is relatively low, allowing it to rapidly transfer the input voltage to the output terminals. This rapid transfer helps to provide pulse width modulation, thus allowing the device to rapidly switch between positive and negative voltages.

The 444CNQ035 rectifier array also features a frequency response of up to 400kHz, which allows it to take advantage of high-frequency pulse-width modulation to deliver high-speed switching operations. Furthermore, the device dissipates very low levels of power, enabling it to provide improved energy efficiency. Finally, the 444CNQ035 rectifier array utilizes a fast reverse recovery time, which helps to further reduce power dissipation and maintain low levels of energy consumption.

The 444CNQ035 rectifier array can be used in a range of applications, including distributed power supply systems, switching and switching regulators, high current dc-dc converters, and in voltage converters. The device is well-suited for managing electric current in digital devices, and it is also useful for maintaining accurate analogue signal levels.

In summary, the 444CNQ035 rectifier array is a highly efficient and compact four-terminal active rectifier device. It features low voltage drop, low power dissipation, low leakage current, and a fast reverse recovery time. The device is designed to control electric current in a circuit and can be used in distributed power supply systems, switching and switching regulators, high current dc-dc converters, voltage converters, and other applications.
