The rectifier is a type of diode intended for use in power supply circuits, which converts alternating current (AC) to direct current (DC). In recent years, rectifier arrays have gained popularity due to their superior performance and low cost. The DGSK20-025AS rectifier is a 4-pin surface mount rectifier array that is used primarily in applications such as power conversion, UPS systems, chargers, and multiple AC/DC application fields. This paper will discuss the application field, working principle and features of the DGSK20-025AS rectifier.

Application Field

The DGSK20-025AS rectifier is designed for applications that require high-efficiency and low noise. This rectifier can be used in a variety of different applications, ranging from motor speed control to solar power to switching power supplies. It is also ideal for use in home appliances, automotive electronics, and other consumer electronics. Additionally, this rectifier is also suitable for use in medical and industrial applications.

Working Principle

The DGSK20-025AS rectifier is a four-pin surface-mount rectifier array. This rectifier is designed to provide direct current (DC) using alternating current (AC). The DGSK20-025AS rectifier uses four Schottky diodes in a bridge configuration to provide rectification. The diodes are arranged in pairs: two diodes for each of the two AC inputs. This allows for high-efficiency power conversion as the two AC inputs are not needed every cycle. The two AC inputs are alternately swapped over each half-cycle, ensuring that the output remains constant.

The DC output of the DGSK20-025AS rectifier is highly stable and efficient due to its low forward voltage drop of 0.35V, an emission current of only 1.5mA, and a reverse leakage current of 0.25mA. This ensures that the output current is constant and within limits even after long durations of operation.
