Introduction

The MBR2040CT is a Diode Rectifier Array which is specifically designed as a replacement for the obsolete MUR2040CT. It consists of two Schottky rectifier diodes which are packaged in a single, leadless, hermetic ceramic surface-mount device. Its utilization range is from 0.4A to 4A, with an operating voltage range of 60V to 200V. It features low forward voltage drop, low diode junction capacitance, and low thermal resistance.

Applications

The MBR2040CT diode rectifier array is widely used in various types of high-resistance, low-loss applications such as power converters, frequency inverters mode converters, DC-DC converters, uninterruptible power supplies, and many more. It is also used in critical switching power converters, high-frequency switching regulators, and audio power amplifiers. The low on-voltage and reverse recovery characteristics enable the MBR2040CT to provide a much higher efficiency compared to other rectifier diodes.

Working Principle

The working principle of the MBR2040CT diode rectifier array is as follows. When an alternating current is applied to its terminals, the two diodes inside the package will conduct alternatingly, turning the AC current into a DC current. The switching sequence of the two diodes is determined by their individual characteristics. Consequently, the rectified current is DC instead of AC, acting as a filter by blocking the AC current.The MBR2040CT diode rectifier array contains two Schottky diodes which are connected in series. This ensures that the forward voltage drop is kept to a minimum, reducing power loss and improveing efficiency. The diodes are constructed on a metal ceramic substrate, which provides excellent thermal performance and robustness.

Conclusion

The MBR2040CT is an ideal choice for a wide range of applications due to its excellent thermal characteristics and high efficiency. Its low forward voltage drop, low diode junction capacitance, and low thermal resistance make it ideal for power converters, frequency inverters mode converters, DC-DC converters, uninterruptible power supplies, and many more. It is also used in critical switching power converters, high-frequency switching regulators, and audio power amplifiers. The working principle of the MBR2040CT diode rectifier array is based on the two Schottky rectifier diodes which are connected in series, ensuring that the forward voltage drop is kept to a minimum. All in all, the MBR2040CT diode rectifier array offers a reliable solution for many applications.
