BY225 is an electronic circuit that converts an alternating current (AC) input into a direct current (DC) output using a bridge configuration of diodes. The purpose of a bridge rectifier is to ensure that the voltage is always positive, even though the input voltage waveform may be alternating in direction. This makes it useful in applications such as power supplies, battery charging, and motor control where a DC voltage is required.

Ready-for-use full-wave bridge rectifiers in a plastic encapsulation.
The bridges are intended for use in equipment supplied from a.c with r.m.s voltages up to 80V and are capable of delivering output currents up to 4,8A.

They are also suitable for use in hi-fi audio equipments and low-voltage industrial power supplies.

The may be used in free air or clipped to a heatsink.

The basic operation of a bridge rectifier is to allow current to flow only in one direction, by using diodes to block any reverse current. The diodes are arranged in a bridge configuration, hence the name “bridge rectifier.” The AC voltage is applied to the diode bridge, and the resulting DC voltage is available at the output terminals.

Bridge rectifiers are commonly used in power supplies for consumer electronics, industrial equipment, and other applications where a DC voltage is needed.
