Diodes Bridge Rectifiers or DBRs are common components in electronic circuitry. They consist of two or more p-n junction diodes connected in series with a common junction at either end. The common junction acting as a two-way gate, allows electric current to flow in one direction only and providing a well-known rectifying characteristic. The two-way gate is referred to as a bridge rectifier.

The traditional diodes used in electronic products include Low-Power & High-Power, Schottky, and Zener Diode (ZD). The Bridge Rectifier is a special type of diode that connects two Diodes in series and creates a diode bridge. A bridge rectifier can have from two up to eight diodes, allowing for more efficient Conventional Rectification.

GBU4A-BP Application Field and Working Principle:

The GBU4A-BP is a bridge rectifier that is widely used across a variety of industries. The bridge rectifier provides a simple and cost-effective way of implementing a bridge rectifier with low-power applications such as AC to DC conversion. It has an efficient full wave rectifying and noise suppressing features.

The GBU4A-BP is a standard, 4-pin bridge rectifier with a maximum current rating of 2.5A. It is suitable for voltage inputs up to 600V, and it also has a high surge current up to 15A. The GBU4A-BP bridge rectifier, with its epoxy coating, can be used in a wide temperature range of -55℃~125℃, and thus is suitable for many different types of applications.

The bridge rectifier is composed of four diodes which are arranged in a specific way to achieve the desired characteristics. The four diodes of the GBU4A-BP are connected in series in the following fashion: two diodes with their anodes facing to the positive power rail, and two diodes with their cathodes connecting to the positive power rail.

When alternating current (AC) flows in either direction through the GBU4A-BP, the two diodes in series with the anodes facing to the positive rail conduct each time in turn and supplies a path for the current to travel. This process allows for the current to be supplied to the load, thus allowing for AC to DC conversion.

The GBU4A-BP bridge rectifier is also capable of suppressing impulses and surges in voltage. This is achieved by the bridge rectifier allowing a greater current to flow through the load and then both pins of the lost source are shorting each other quickly. The current is shorted between the anode and the cathode, resulting in a lower voltage and the suppression of any noise or impulses that would otherwise travel along the power line.

In conclusion, the GBU4A-BP bridge rectifier finds usage in a wide array of applications ranging from power supplies and converters to motor control and communications. The bridge rectifier is cheap, reliable and implements a full wave rectification process that converts AC to DC voltages or currents in an efficient and cost-effective manner.
