Diodes - Bridge Rectifiers are used in many of today\'s applications, from power supplies to motor drives, data communications to servo drives. When it comes to selecting the right diode, it important to understand the application field and working principle of the diode.

The BU-2008-E3/45 diode is a medium current diode offering a high performance rectifier for various power semiconductor operations. Originally developed for telecom applications, it was specifically designed for bidirectional applications and active protection in motor drives to ensure a highly reliable power rectifier. Its dielectric properties also make it ideal for use in many industrial and automotive applications.

Let\'s look at the field of operation and the inner workings of the BU-2008-E3/45 diode. This diode operates in the field of high voltage, up to 900 volts. Its peak reverse voltage rating is 1.5 KV, and it can handle up to 3 Amps of DC Continuous / Intermittent current. It is rated as a fastwitching diode, meaning it can cycle between on and off very quickly, which is useful for applications where a rapidly changing signal is needed. On the flip side, it also means it can\'t handle an overload, due to its fast switching properties.

The BU-2008-E3/45 is a bridge rectifier which means that it provides a full-wave rectification of an alternating current into a direct current. It does this by having two sets of resistors joined together to provide a complete “bridge” - a full-wave rectifier. As it converts an alternating current into a direct current, it also allows for a smooth and efficient output.

The BU-2008-E3/45 contains four diodes that are configured in a full-wave bridge rectifier and it has a thermal characteristic of 75°C/W when reverse biased. This thermal characteristic is important as it can help ensure that the bridge rectifier operates at a lower temperature, which can help to improve the reliability of the diode.

The diode also offers a wide range of protection and safety features. It has a protection circuit that helps to protect it from over-temperature, over-current and over-voltage, helping to ensure the safe operation of the bridge rectifier. It also includes a reverse polarity protection, which helps to limit the current in the reverse direction and a snubber circuit that helps to reduce the EMI generated from the diode. Finally it also has a very low resistance including a very low forward voltage drop.

In summary, the BU-2008-E3/45 diode is a medium current diode offering a high performance rectifier for various power semiconductor operations. It offers a wide range of protection features and benefits, including a wide operating voltage range, high peak reverse voltage rating, protection circuit, reverse polarity protection and a snubber circuit.

It is ideal for bidirectional applications and active protection in motor drives, data communications and many industrial and automotive applications.
