SBR10E45P5-13 Application Field and Working Principle

Introduction

SBR10E45P5-13 is a diode rectifier specially designed for General Purpose applications. It is a Silicon Bridge Rectifier that provides a rugged and economical solution to two popular application fields. In this article, we will discuss the application field and working principle of the SBR10E45P5-13.

Application Field

The SBR10E45P5-13 is mainly used in two primary application fields: AC-DC converters, and heavy load power supplies. In AC-DC converters, the SBR10E45P5-13 is used as a rectifier for both forward and reverse currents, providing ideal operation in both directions. The diode’s high forward current and low reverse leakage current make it an ideal choice for heavy load power supplies. In these applications, the rectifier helps reduce the need for bulky heat sinks and helps to ensure a long service life.

Working Principle

The SBR10E45P5-13 features a silicon-bridge rectifier configuration. In this configuration, the diode consists of two pairs of silicon-controlled rectifiers mounted on an electrically insulated substrate. The pairs of rectifiers are connected in anti-parallel and can be used to perform bidirectional current rectification. When direct current is applied, the diode produces a voltage drop of about 0.7V. In forward conduction mode, the diode acts like a single rectifier and will draw current from the input directly through the rectifier bridge. This causes a voltage drop across the rectifier bridge, resulting in an output voltage of approximately 0.7V lower than the input voltage. In reverse conduction mode, the diode will work like an open switch and will not draw any current from the input. This maintains the same voltage across the rectifier bridge and provides the same output voltage as the input.

Conclusion

The SBR10E45P5-13 diode rectifier provides a rugged and economical solution for AC-DC converters and heavy load power supplies. The silicon bridge configuration combined with the diode’s low forward voltage drop and low reverse leakage current makes it an ideal choice for these applications. The diode also ensures a long service life and helps reduce the need for bulky heat sinks.
