A rectifier circuit is used for converting Alternating Current (AC) to Direct current. Many rectifier circuit configurations are available including half wave rectifier, full wave rectifier, bridge wave rectifier, single phase, three phase, and controlled rectifier, each configuration has its own pros and cons. Bridge rectifier configuration is the most popular configuration due to the advantages including high efficiency, higher output power, low ripple factor and exception of center tap transformer.

D25XB60 is a silicon bridge rectifier integrated circuit. It is a single phase rectifier that handles the maximum peak reverse voltage of 600 V.

Working Principle

Many electronic applications require regulated DC and the most reliable way to provide DC is via rectification of the AC. Bridge rectifier configuration is the widely used to provide DC due to certain advantage that are mentioned above. 

Bridge rectifier circuit requires four diodes, which are generally represented in shape of diamond/ bridge on the circuit diagrams hence called bridge rectifier. AC signal consists of positive half cycle and negative half cycle, during the positive half cycle two of the four diode of bridge configuration conducts and for the negative half cycle other two diode of the bridge rectifier conducts. By the virtue of this configuration current is allowed to pass through the circuit in only one direction and DC is produced. A bridge rectifier circuit can be formed using discrete electronic components however off the shelf integrated circuit like D25XB60 are also available
