Diodes - Rectifiers - Single

The SB520E-G rectifying diodes is a single diode designed to provide a low power dissipation and a high reverse blocking voltage rating. This is done through the use of a Schottky barrier or “hot-nix”. The SB520E-G has a reverse voltage tolerance of 40 volts and a maximum current rating of 500mA. It is designed for use as a rectifier in power transformers, and other high voltage rectifying applications.

Application Field

The SB520E-G is commonly used in power supplie, battery chargers, and external power supplies. It is used in the process of rectifying the alternating current from power supplies and battery chargers, and can also be used in the regulation and control of the AC mains. It is also used as a protective device in equipment for over voltage protection and for switching high power loads.

Working Principle

The working principle of the SB520E-G is based on the construction of a Schottky barrier diode. The Schottky barrier diode is a device where the rectifying junction is formed between a metal electrode, such as molybdenum, and semiconductor material, most commonly silicon or germanium. The fabrication of the junction is done in such a way that the metal electrode acts as a low resistance connection between the two materials, allowing the current to flow in only one direction.This process of unidirectional flow of the current allows for the effective regulation and control of the AC current, as well as providing the overvoltage protection. As a result, the SB520E-G acts as a rectifier and provides a high, low-loss voltage step-down. This rectifier can also be used to regulate and control the input voltage of a power supply, allowing less voltage to be stepped down.The SB520E-G is capable of providing a high reverse-blocking voltage rating of 40 volts and offers a maximum current rating of 500 mA. It can handle a surge current of up to 600 mA, which makes it ideal for applications that require high power switching.

Performance Benefits

The SB520E-G offers several advantages, including a low leakage current, a low thermal resistance and a high frequency response. It also offers a high reverse-blocking voltage rating of 40 volts and can handle up to 600 mA of surge current. The SB520E-G also offers a wide operating temperature range, from -40°C up to 140°C, which makes it suitable for applications that require a wide range of temperatures to perform efficiently and effectively.In addition, the SB520E-G has a low-voltage differential, which means that it can handle electrical noise from power sources, helping to reduce interference and further improving the performance of the rectifier. It also has a low forward voltage drop, which helps to reduce the power losses associated with a rectifying circuit.

Conclusion

The SB520E-G rectifying diode is a great choice for use in power supplies, battery chargers, and other high voltage rectifying applications. It is capable of providing a high reverse-blocking voltage rating of 40 volts, with a maximum current rating of 500 mA and a surge current rating of 600 mA. It also has a low thermal resistance, a low leakage current, a low voltage differential and a wide operating temperature range. All of these features make the SB520E-G ideal for use in a variety of applications.
