SBRT05U20LPS-7B

Introduction

The SBRT05U20LPS-7B is a single rectifier diode, which is commonly used in numerous applications ranging from AC/DC power supply conversion, DC/DC power conversion, RF/IF signal rectification and other applications where rectification is needed. This component typically achieves a peak forward rectified current of 2A and a reverse leakage current of 100µA. The component’s package is a miniature SOIC-7 (Small Outline Integrated Circuit) with a plastic surface mountable version. This article will discuss the common application fields and practical working principles of the SBRT05U20LPS-7B diode.

Application Field

The SBRT05U20LPS-7B diode is primarily used in AC/DC and DC/DC converters, where it is used in pairs as a full-wave bridge rectifier. In this application, the diodes are connected inversely across two pairs of terminals and configured so that when a positive half-cycle of AC current passes through one pair of terminals, one pair of diodes conduct allowing current to flow in one direction. Similarly, during the negative half-cycle of AC current, the other pair of diodes will conduct and current will flow in the opposite direction. This results in a full-wave rectified output that can be used as a DC current.

Apart from converters, the SBRT05U20LPS-7B diode is also commonly used for other rectification and switching purposes such as RF/IF signal rectification, rectification of pulsed currents, voltage multipliers, Zener diode circuits, and switching regulators. Due to its miniature size and low leakage, it has become a very popular choice for these applications.

Working Principle

The working principle of the SBRT05U20LPS-7B diode is relatively straightforward. The diode is constructed from a semiconductor material such as silicon. This material features a naturally rectifying, or unidirectional, property that allows current to flow through it in only one direction (from anode to cathode). Therefore, when an electric potential is applied across the terminals of the diode, current will flow in the forward direction and none in the reverse direction.

The diode’s peak forward rectified current, I_F, is the maximum current that the diode can safely and continuously handle. Likewise, the reverse leakage current, I_R, is the maximum current that can flow through the diode in the reverse direction. For the SBRT05U20LPS-7B, this peak current is 2A and the leakage current is 10µA, respectively.

Conclusion

In conclusion, the SBRT05U20LPS-7B diode is a popular choice for numerous AC/DC and DC/DC converter applications due to its miniature size and low leakage current. Furthermore, its unidirectional properties make it well-suited for signal rectification, switching, and other rectification applications. Understanding its common application fields and practical working principles is essential to designing an efficient and successful circuit.
