GBU8K-BP application field and working principle

GBU8K-BP is a bridge rectifier diodes module, which is widely used in various AC to DC applications. It is an 8-pin metal case packaged diode. The modules have low forward voltage drop, low thermal resistance and can handle a surge current of up to 20A.

Bridge rectifiers are widely used in power supplies and battery chargers, especially in mobile applications. In general, a diode bridge rectifier has four ports (input, output, and two reference). The input port of the rectifier can be either an AC or a DC voltage. The output port is the rectified AC or DC voltage.

Bridge rectifiers are especially efficient when rectifying AC current with low frequency, due to their low forward voltage drop. The module also has a low thermal resistance and can handle high current surge, up to 20A. The GBU8K-BP bridge rectifier also has low reverse leakage current, which makes it ideal for applications where high precision is needed.

The working principle of a diode bridge rectifier can be explained as follows. Diodes are used to ‘convert’ alternating current (AC) into direct current (DC) by allowing electricity to flow only in one direction. A diode bridge rectifier consists of four diodes stacked in a bridge configuration.

When the AC voltage is applied to the bridge rectifier, it removes the negative part of the AC wave and allows only the positive part of the wave to pass through the bridge. This results in direct current (DC) voltage being produced at the output port.

The GBU8K-BP can also be used in reverse to invert a DC voltage. By connecting the AC voltage supply to the opposite end of the rectifier, the DC voltage can be inverted and passed through the diode bridge rectifier.

The GBU8K-BP is ideal for applications requiring high precision and low forward voltage drop, particularly in mobile applications. Its low thermal resistance and ability to handle large surge current makes it a popular choice in many applications.
