MSB25MH-13

Diodes - Bridge Rectifiers are indispensable components for many applications. A Bridge Rectifier, also known as a bridge rectifier diode, is a four-terminal, two-stage device that converts alternating current (AC) from a power source into direct current (DC). The MSB25MH-13 Bridge Rectifier diode, produced by Fairchild Semiconductor, is one of the most popular devices among today’s customers, both for its easy application and superior performance. Here we will explain the MSB25MH-13 application field and working principle.

What is MSB25MH-13 Bridge Rectifier?

MSB25MH-13 is a three phase bridge rectifier module, which serves as a full-wave rectifier designed with discrete components, including a diode bridge, a heatsink, and a capacitor module. The module is usually packaged in an electronic module with an insulation shell. It has an efficient design, yielding high current capability, high voltage stability and long working life. Moreover, its maximum forward current, reverse current, and reverse voltage are respectively 25A, 5mA and 100V.

Application of MSB25MH-13

Since the MSB25MH-13 Bridge Rectifier offers good electrical properties and is highly reliable and safe, it has a wide range of applications. It is most suitable for applications requiring high efficiency and low power dissipation, such as DC power supplies and DC motor drives. Furthermore, it is particularly effective in battery chargers, air-conditioner motor drives, halogen lights and solar power inverter applications.

Working Principle of MSB25MH-13

The working principle of the MSB25MH-13 Bridge Rectifier can be best understood by examining the electronic module. Basically, the module consists of four diodes connected in a bridge circuit, which are arranged in a square such that each diode connects two terminals. Each terminal is labeled as A,B, C, and D. When AC power is applied to the terminals A and B, current flows from A to B through two diodes making up the bridge circuit — one a negative polarity and one a positive polarity. The current then flows from the positive diode to C and the negative diode to D, effectively forming a “square” of current.

When the AC input to A and B has zero potential, current stops flowing through the bridge circuit. However, when one of the polarity of the AC input changes, current will again flow through the bridge circuit in the same direction, allowing for continuous DC output. The same operation occurs inversely, when current is flowing in the opposite direction. This operation is the core function of the Bridge Rectifier, converting an AC input into a DC output.

Conclusion

The MSB25MH-13 Bridge Rectifier Diode is one of the most popular devices today due to its high performance, efficient design, and superior reliability. It is suitable for a variety of applications demanding high efficiency and reliable and safe power supplies. Further, its electronic module consists of four diodes connected in a bridge circuit and arranged in a square, which is ideal for converting an AC input power into a DC output power. In short, the MSB25MH-13 Bridge Rectifier Diode is an excellent choice for those needing a higher quality, reliable and safe product.
