A bridge rectifier is a device that uses four diodes to change alternating current (AC) to direct current (DC). The B125C800DM-E3/45 is a biased, 800V, axial-leaded, single- phase bridge rectifier with a maximum average forward current of 125A, and a maximum reverse surge current of 800A.

Application Field

B125C800DM-E3/45 bridge rectifiers are mainly used in power supplies and general purpose power rectification applications. They are also used in converters, solar inverters, UPS systems, power supplies, and other power applications where current rectification is needed. They may also be used in a wide variety of other power electronics applications.

Working Principle

A bridge rectifier is made of four diodes connected in a bridge configuration in order to convert an alternating current (AC) to a direct current (DC). The four diodes are arranged so that only two will conduct current at any given time. This means that every time the AC current polarity changes, the diodes switch positions, and current is conducted in the opposite direction.

When the input AC voltage is applied to the bridge rectifier, the diodes conducts current in only one direction. This causes the output DC voltage to be the same magnitude as the input AC, but with a much higher average value than the average AC voltage, as half of the AC sine wave is not conducted. The frequency at the output is the same as the input frequency.

The advantage of the B125C800DM-E3/45 bridge rectifier is its high surge currents, with a maximum surge current of 800A. This allows for higher power ratings of the device, and increased efficiency in power rectification applications.

The B125C800DM-E3/45 bridge rectifier also has a higher temperature range rating than other bridge rectifier devices, with a minimum operating temperature of -55C, and a maximum of +125C. This allows for a wide range of operating temperatures when the device is being used.

In addition, the B125C800DM-E3/45 bridge rectifier has a higher forward and reverse voltage rating than other comparable devices, with a maximum forward voltage rating of 800V, and a maximum reverse voltage rating of 600V. This makes it suitable for a wide range of applications where higher voltages are required.

Overall, the B125C800DM-E3/45 bridge rectifier is a high quality device designed for use in a variety of power rectification applications. Its high surge current and wide temperature range make it suitable for a range of applications, while its high voltage ratings make it suitable for applications with higher voltages. Furthermore, its axial-leaded design makes it easy to install and use.
