Diodes - Rectifiers - Arrays

For those looking to increase their electronics knowledge and find a useful part, 84CNQ040 rectifier is a great option. This device is an integrated circuit rectifier array with four outputs and an isolated mounting plate. In this article, we\'ll look at what 84CNQ040 rectifier application field and working principle are.

Application Field

The 84CNQ040 rectifier array is primarily used in power-related circuits, including DC-DC converters, DC-AC inverters, switching power supplies, and low-voltage power supplies. It is also commonly used in battery charging systems, and other circuits like rectifier bridges and switching circuits. The array is not only found in regulating and power circuits; it is also a great option for signal processing and digital logic applications, as it can easily convert AC signals to DC signals.

The array is a great choice for those who need an integrated solution for rectification. With just three components, a bridge rectifier, 1N4007 diodes, and the 84CNQ040 IC, the rectifier circuit can be easily built and implemented in a robust way. It offers tremendous advantages over individual diodes, as it reduces the number of external components, offers a cost-effective solution, and simplifies the rectifier design.

Working Principle

The 84CNQ040 rectifier array consists of four individual rectifier diodes that work together to convert AC voltage to DC voltage. The array is triggered by a single-phase or two-phase pulse-width modulation (PWM) signal, which causes the gate of the rectifier diodes to turn "on" and "off" at the appropriate times. When the gate turns "on," the rectifier diode conducts current, and when it is "off," the diode does not conduct current. This process is repeated for each diode in the array in order to provide rectified DC voltage.

This type of rectifier array provides increased efficiency as fewer components are needed, and the entire array is mounted on one isolating plate, which helps reduce size, cost, and complexity. It also helps reduce noise, as the gate signals prevent unwanted power flow in the reverse direction. Additionally, the 84CNQ040 can help increase accuracy and reliability, since it is designed to rectify signals with up to 339V of reverse voltage, and can handle up to 1.5A of forward current.

Conclusion

84CNQ040 rectifier array is an ideal choice for those who need an integrated solution for rectification. It offers cost savings, increased efficiency, and improved accuracy and reliability. This rectifier array is primarily used in power-related circuits, including DC-DC converters, DC-AC inverters, switching power supplies, and low-voltage power supplies, but it can also be used in signal processing and digital logic applications.
