Diodes, generally known as bridge rectifiers, are devices typically used to either permit or block the flow of electrical current. The GBU402TB is a 400V bridge rectifier diode that is typically used to convert alternating current (AC) to direct current (DC). This type of diode is composed of four semiconductor diodes connected in series in a \'bridge\' configuration, hence it being referred to as a bridge rectifier.

The application field of the GBU402TB includes, but is not limited to, charge pumps and power supply integrated circuits, notebook computers, laptop computers, servers and other personal computers, and equipment that requires isolation between two systems. GBU402TB bridge rectifiers are most often used in AC power supplies, battery chargers, industrial DC motors, and automotive applications. Withstanding up to a 1 amp surge current and having a total conduction loss of less than 0.4W, it’s easy to see why the GBU402TB is preferred for many electrical applications.

The structure of a bridge rectifier includes a pair of opposite-polarity P-N junction diodes that allow current to flow in either direction through an alternating current (AC) source. The working principle of a bridge rectifier, whether it’s the GBU402TB or any other diode, is relatively simple. Electronic signals enter the bridge rectifier through two wire inputs, with positive going signals passing through the positive-connected diode, while the negative-directed signals passing through the negative-connected diode.

The output of the bridge rectifier is a DC signal, as the incoming AC signals have been ‘broken’ down or ‘rectified’. One of the main uses of a bridge rectifier is to convert AC from one voltage level to another. This is often used when the AC source’s voltage needs to be stepped down, and is done by controlling the input current of the rectifier, which then maintains a fixed AC or DC output voltage.

A bridge rectifier is also widely used in filters. Here, a bridge rectifier is provided with a circuit that ‘smoothens’ out the flow of DC to produce a constant voltage and current, depending on the load. This type of filter, referred to as a bridge filter, uses inductors and capacitors to ensure high-quality rectified output.

In conclusion, the GBU402TB bridge rectifier is a widely used electronic device in the commercial, industrial and automotive sectors. It is mainly used as a power rectifier to convert alternating current to direct current and for powering DC motors. It also finds many applications in filters, where it works with inductors and capacitors to provide high-quality rectified output.
