Introduction

The 84CNQ045sMS2 is a rectifier diode array. It is a four diode, Schottky diode with a maximum forward current rating of 45A. This diode array is used mainly in automotive and industrial applications, where it provides improved system performance when compared with conventional diodes. In this article, we will discuss the common applications of the 84CNQ045sMS2 as well as its working principles.

Applications

The 84CNQ045sMS2 is a popular choice for automotive and industrial applications due to its high power handling capability and low forward voltage drop. It is often used as a voltage doubler for automotive charging systems, providing an efficient way to increase the output power compared to conventional rectifiers. Moreover, it is also commonly used in automotive ignition systems to provide current limitation and protection of sensitive components. Furthermore, in industrial applications, the 84CNQ045sMS2 is frequently used in motor control circuits to provide overcurrent protection, current limiting and reverse protection.

Working Principles

The 84CNQ045sMS2 is composed of four Schottky diodes connected in series. In a schematic diagram, the diodes are represented as two separate diodes in parallel, with the anode of each set of two diodes connected together. The cathode of one set of diodes is connected to the anode of the other set. This configuration allows the diode array to handle up to 45A of forward current. The Schottky diodes have a low forward voltage drop, resulting in an improved efficiency when compared with conventional rectifiers. Additionally, the construction of the diode array provides inherent reverse polarity protection, reducing the chance of damage due to reverse voltage.

Conclusion

The 84CNQ045sMS2 is a four diode Schottky diode array with a maximum forward current rating of 45A. It is typically used in automotive and industrial applications, such as voltage doublers, motor control and automotive ignition systems. The low forward voltage drop of the Schottky diodes provides better efficiency compared to conventional rectifiers and the diode array also provides reverse polarity protection.
