DSA70C200HB Application Field and Working Principle

DSA70C200HB is one of the most commonly used semiconductor products, which can be classified into the group of diodes, rectifiers and arrays. This component is a high power rectifier diode array consisting of four silicon devices. The component has a wide application field and could be used in multi-channel power applications, such as high-voltage industrial systems and high-power switching power supplies.

Applications

DSA70C200HB is most commonly used for energy-saving applications, such as high-power switching power supplies, AC/DC rectification, amplification and rectification of large power system voltage. The component can be found in various high power electronic systems, such as automatic control systems, calculation systems, telecommunication systems, medical equipment, display systems and photoelectric sensor systems. The device is also suitable for several types of data processing systems. The main purpose of the part is to maintain power stability when handling large power data.

Working Principle

The DSA70C200HB consists of four silicon components that are positioned next to each other in a package. The device has a low forward voltage drop, high peak current and high surge current capability making it suitable for high power rectification applications. Additionally, it also offers high current carrying capability, low on-state voltage and moderate switching speed. The basic working principle of the DSA70C200HB is that it carries out four distinct electronic functions. The first is a rectification process, whereby the incoming alternating current is converted into a direct current. The second is a switching function, whereby the four individual components of the diode array open or close based on whether the AC current is in the positive or negative phase. In addition, the diode array allows for a current flow mainly in one direction while blocking the current’s passage in the opposite direction. Lastly, the device can provide a certain level of isolation between the output and input terminals of the device, in order to limit their contact to only one point.

Conclusion

DSA70C200HB is a high power rectifier diode array consisting of four silicon devices, which is widely used in high-power switching power supplies, high-voltage industrial systems and various other electronic systems. The device is mainly used for energy-saving applications, mainly because it has low forward voltage drop and high surge current capability and can support large power data. Additionally, DSA70C200HB has four distinct electronic functions, including rectification, switching, current flow limiting and isolation.
