Diodes are fundamental in electronics. They are the core components for rectifying alternating current, providing power supply for a circuit, or even building voltage or current regulators. Diodes can also be combined into an array, as seen in the UB20BCT-E3/8W, which is designed for applications that require high-current rectification, including AC-DC power supplies, DC-DC converters, LCD displays, and integrated transistor regulators. In this article, we will explore the application field and working principle of the UB20BCT-E3/8W.

The UB20BCT-E3/8W is a high-current rectifier array that consists four individual 1A Schottky diodes configured in a common anode configuration. It can handle 1A of peak current and 0.5A of average current. The rectifier array has a breakdown voltage of 30V and a forward voltage drop at rated current of 0.45V. These performance data make it suitable for a range of medium power applications, especially automotive applications.

The UB20BCT-E3/8W has a very versatile application field. Due to its low power consumption and high current capabilities, it is ideal for use in AC-DC power supplies, DC-DC converters, and other circuits that require rectification. For example, it can be used to build a voltage regulator, with the diodes forming a bridge that rectifies the incoming AC signal into two DC outputs with different polarities. It can also be used in LCD displays, as it can be easily combined with a transistor to form an integrated voltage regulator. Finally, the UB20BCT-E3/8W can be used for switched-mode power supplies, where it helps regulate the power supply and provide tight control on current and voltage.

The UB20BCT-E3/8W works on the principle of rectification, as is the case for all rectifiers. At its core, a rectifier consists of two diodes connected in series and two other diodes connected in parallel, with the anode of one diode and the cathode of the other connected to the anode of the second diode and the cathode of the first diode to the anode of the third diode, respectively. When an alternating current is applied to the rectifier, the diodes conduct current alternately in accordance with the direction of the current. As a result, a DC output is obtained.

In addition to rectification, the UB20BCT-E3/8W also provides protection against reverse polarity. This is achieved using a reverse-voltage protection that prevents current from entering the device when the source voltage is backwards or the ground lead is connected to supply. This offers greater reliability and improves the lifespan of the device.

The UB20BCT-E3/8W combines the convenience of a single part with the performance of four discrete diodes to form an ideal rectifier for automotive and industrial applications. It is a perfect solution for medium power applications due to its efficiency, low power consumption, and high current capabilities. With its versatile application field and reliable protection against reverse polarity, the UB20BCT-E3/8W is the perfect choice for rectifying applications.
