Introduction

Diodes are components that control the flow of electricity by directing current in one direction. They are used in a variety of applications, such as rectification, signal filtering, and voltage clamping. Rectifier arrays are a type of diode, composed of multiple diode elements that work together to produce a higher current handling capacity and more efficient rectification. MEK75-12DA is a type of rectifier array which combines twelve individual diodes in one package. This makes it a perfect choice for many power supply and motor control applications.

Application Fields

MEK75-12DA rectifier arrays have a wide range of applications. They can be used in AC-DC power supplies, flyback converters, continuous and discontinuous mode buck converters, lighting control, motor control, and more. The package contains two terminals for each diode, which allows for both single-phase and three-phase rectification. In AC-DC power supplies, MEK75-12DA rectifier arrays improve reliability and reduce noise. By controlling the power flow, these rectifier arrays reduce the requirement for transformer sizes, allowing for smaller and more efficient designs. In motor control applications, MEK75-12DA rectifier arrays are used to filter and control voltage spikes that can cause motor malfunction.

Working Principle

MEK75-12DA rectifier arrays work according to the same principle as individual rectifier diodes. When voltage is applied to the anode, the diode conducts and allows current to flow, whereas when voltage is applied to the cathode, the diode blocks the current. This allows the MEK75-12DA rectifier array to control current flow in one direction, enabling AC-DC power conversion and motor control.A single phase rectifier array is composed of six diodes connected in a “bridge” circuit, and a three phase rectifier array is composed of eighteen diodes connected in a “grand bridge” circuit. Depending on the application, the MEK75-12DA rectifier array can be connected as a three phase rectifier array to support higher current handling capacity. Connecting the rectifier array in this way improves the efficiency of rectification, allowing for more reliable operation.

Conclusion

MEK75-12DA rectifier arrays are powerful multi-diode components that provide reliable, efficient rectification and current control. They can be used in a variety of applications from AC-DC power supplies to motor control. The two terminal design allows for both single-phase and three-phase rectification, and the efficient grand bridge circuit design enables higher current handling capacity.
