A diode array is a single package comprised of two or more diodes connected to each other. The MD18110A-DKM2MM is an ultrafast recovery, low leakage, and low forward voltage drop diode array from Diodes Incorporated. It is specifically designed to reshape, regulate, and limit overvoltage transients in industrial and consumer applications. In this article, we will discuss the features and applications of the MD18110A-DKM2MM and its working principle.

Features

The MD18110A-DKM2MM diode array has an ultra-fast recovery time of 35ns, and a low leakage current of 5μA. These features make this diode array suitable for high-frequency switching applications. The array is also designed with low forward voltage drop (1V) to provide greater circuit efficiency.

This device is available in a two-lead, small surface mount package (SMA). The MD18110A-DKM2MM is designed with a maximum reverse voltage of 1000V and a maximum peak forward current of 5A. The operating temperature range is -55°C to +150°C, making it ideal for use in a wide variety of industrial and consumer applications.

Applications

The MD18110A-DKM2MM diode array is primarily used for reshaping, regulating, and limiting overvoltage transients. This device is often used in automotive and consumer electronics applications for EMI/RFI filtration and switching power supplies. It is also used in DC-DC converters, data communication systems, and industrial machinery.

Working Principle

The working principle of the MD18110A-DKM2MM diode array is fairly straightforward. When a voltage is applied to the array, current flows through one diode while the other diode is blocked. The current then flows through the two diodes, keeping the same configuration. This provides continuous conduction of the current within the device, regulating and limiting the overvoltage transients.

As the voltage across the array rises, the device begins to resist the flow of current. This results in a lower forward voltage drop, allowing the device to function more efficiently and continuously. The reverse voltage working of this diode array is such that when the voltage across the device decreases, it will become more resistant to any further decrease in current, thus preventing any further overvoltage transients.

The features of the MD18110A-DKM2MM diode array make it an ideal choice for a variety of applications. The combination of low forward voltage drop, low leakage, and ultrafast recovery time makes this device suitable for high-frequency switching applications. It is also an excellent choice for automotive, consumer electronics, and industrial applications due to its temperature range, size, and operating voltages.
