Introduction

SD103BWS-7 is a kind of single rectifier diode featured with high surge current capability. It operates in a wide range of voltages from 10V to 100V and can be used in a variety of application fields such as power conversion, signal rectification and switching applications. This article will provide a brief overview of the application fields and the working principle of SD103BWS-7 to help readers gain more understanding of such a solid state device.

Application of SD103BWS-7

The SD103BWS-7 is a popular choice for a variety of rectification applications. It is suitable for use in environments with a wide range of voltages due to its wide voltage range. It is specifically designed to serve as an efficient full-wave or bridge rectifier, providing high surge current capability to suppress noise and power loss due to bridge rectification voltages. This makes it suitable for various voltage conversion and signal rectification applications. It also has excellent power handling capabilities and able to perform even under high temperatures and switching applications, making it ideal for use in motor control systems. Furthermore, it can be used in solar powered applications such as converters, charge controllers, and inverters. Its low-forward voltage drop also contributes to its relatively wide range of applications.

Working Principle of SD103BWS-7

The SD103BWS-7 utilizes a p-n junction formed from a combination of Metal Oxide Semiconductor (MOS), silicon, and Poly-silicon, which enables the device to limit the current it absorbs from a circuit. When the p-n junction is connected to a positive current and the contact is negative, electrons are shifted from the negative contact and are attracted to the positive contact. Conversely, when the p-n junction is connected to a negative current and the contact is positive, electrons are attracted to the negative contact. The SD103BWS-7 is a full-wave rectifier, meaning that it can be used in both full-wave and bridge rectification applications. This enables it to provide efficient power conversion and signal rectification performance. In a full-wave application, the p-n junction is connected to a positive-leading and negative-trailing sine wave of alternating current. The negative current creates a forward voltage drop, and the positive current creates a reverse voltage drop. In a bridge rectification application, the p-n junction is connected to alternating currents which have leads of the same sign. The diode will absorb the forward voltage drop, and the bridge rectification will generate a steady current. This rectified current is then used in downstream circuits.

Conclusion

The SD103BWS-7 is a popular choice for a number of power conversion and signal rectification applications. It is suitable for use in environments with a wide range of voltages due to its wide voltage range. Moreover, its P-N junction, which enables the device to limit the current it absorbs from a circuit, makes it suitable for both full-wave and bridge rectification applications. All these features make it an excellent choice for a variety of applications such as solar panel systems, motor control systems, and voltage converters.
