DBLS204GHC1G

Diodes - Bridge Rectifiers

The DBLS204GHC1G is a bridge rectifier in the form of a Diode bridge. Bridge rectifiers are widely used in power supplies, providing Galvanic isolation and allowing single-phase AC supplies to be converted into DC supplies. Bridge rectifiers are preferred over Full Wave Rectifiers due to their ability to handle higher AC voltages.

Application field

The DBLS204GHC1G is a high speed, low voltage rectifier, making it ideal for a variety of power related applications from simple AC to DC power conversion to battery charging circuits and motor speed control applications. It can also be used for board current limiters, LLC resonant converters, wireless-chargers for small electronic devices, and mobile applications such as audio amplifiers and cell phones.

Working Principle

A bridge rectifier consists of four diodes arranged in the form of a bridge. The DBLS204GHC1G uses four silicon diodes, each capable of conducting a current of up to 5A. When an AC voltage is applied across the bridge, the diodes conduct alternately, rectifying the AC voltage into a pulsating DC voltage. This is further filtered and regulated to produce a smooth DC output.

The main advantage of a bridge rectifier over a Full Wave Rectifier is that the bridge rectifier can handle higher voltages. The high-speed diodes in the DBLS204GHC1G are capable of handling up to 600V of reverse-blocking voltage, allowing for applications such as AC to DC power conversion. This component also has high temperature ratings of up to +150°C, allowing it to be used in high temperature applications.

Conclusion

The DBLS204GHC1G is an ideal component for a variety of power related applications. It features a bridge rectifier with four high-speed diodes capable of handling up to 600V of reverse-blocking voltage and a temperature rating of up to +150°C. This component is ideal for AC to DC power conversion in general power supplies, battery charging circuits, and motor speed control, as well as LLC resonant converters, wireless-chargers and other low voltage applications.
