Diodes - Bridge Rectifiers:

Motion control and power electronics have become an integral part of modern life. A wide range of technology interfaces and components are used in this field, one of the most popular being a bridge rectifier.

The BU25H06-E3/A bridge rectifier is a powerful, single-piece solution for DC power supply applications. It is a three-phase full wave control grade rectifier with a high power density and superior thermal performance.

This rectifier consists of an optimized combination of diodes, MOSFETs, and gate drives that offer a wide range of protected driving characteristics. The BU25H06-E3/A also consists of an integrated voltage collapse temperature sensing device that can be used to protect against thermal runaway and maintain a stable operating point.

Application Field:

Commonly used for DC power supplies, the BU25H06-E3/A has several applications across different industries from power tools and other motor speed control applications, medical electronics, industrial automation and process control systems, to household appliances and energy storage systems.

This bridge rectifier also plays an integral role in applications where a high-power constant DC output is required. Its combination of excellent current delivery, temperature sensing, and protection features makes it suitable for demanding applications.

Working Principle:

The BU25H06-E3/A is a self-driven and protected bridge rectifier. It is able to provide a solution to many single-phase full wave or three-phase full wave rectifier applications up to 2.5 kW. The device is built by connecting a series of diodes together in a bridge configuration to convert the AC input voltage into a DC output voltage.

The device also includes a temperature sensing device (TSD) that provides temperature protection against thermal runaway caused by any sudden increase in the device’s temperature. This TSD triggers a fault signal if the temperature exceeds a set threshold, and then shuts down the bridge rectifier. This safety feature allows users to employ the BU25H06-E3/A for high power applications.

The BU25H06-E3/A can accept an input voltage range of 9-14V for single-phase full wave rectification, and 18 to 26V for three-phase full wave rectification. It can deliver an output current up to 25A and a maximum power of 2.5 kW.

The BU25H06-E3/A has a low-profile package design, with a total height of 2.5mm and a minimum component area of only 7.5 cm2. This makes it easy to integrate with other components and systems. It also supports over-voltage and over-temperature protection, as well as under-voltage lockout and reverse current protection. This improves the system’s efficiency and increases the reliability of the rectifier.

Overall, the BU25H06-E3/A is an extremely versatile device that offers a high-power solution for a variety of DC power supply applications. With its wide range of features, this bridge rectifier can provide a reliable and efficient power source for a number of different industries.
