The VB20120SG-E3/4W is a high power, single phase, bridge rectifier ideal for applications that require high power conversion from AC to DC. The device is capable of handling up to 20 amps of continuous current and can easily convert AC current to desired DC voltage for applications such as general power rectification, UPS systems, switch-mode power supplies and AC-DC power converters.

Application Field and Working Principle

The VB20120SG-E3/4W is designed to be used in a wide range of AC-DC applications, most notably, power rectification and power factor correction. The device is rated for up to 20A continuous current (at a maximum of 250V AC), allowing it to be used in a number of applications that require high-power conversion from AC to DC. It is ideal for applications such as UPS systems, switch-mode power supplies, AC-DC power converters, and other general power rectification applications.

The device features four Schottky barrier rectifiers arranged in an H-bridge configuration and is able to efficiently convert AC current to a desired DC voltage. The Schottky barrier rectifier is a type of semiconductor that is used in a variety of applications to efficiently rectify AC current to DC. It works by using a thin layer of conductive material (typically doped silicon) to form a diode-like junction, which causes the voltage across the diode to drop so that the output voltage is lower than the input voltage. This lower output voltage is used to produce a direct current. The Schottky barrier rectifier is used in applications where the output is not expected to change in polarity, such as when the output is fed directly to a load that requires the same polarity current rectification.

The device also features a fast and accurate temperature protection feature. This feature ensures that the diode does not overheat due to extended current flow, preventing possible damage. The device also features high surge capability, allowing it to handle higher voltage changes, as well as a low forward voltage to reduce power loss.

Overall, the VB20120SG-E3/4W is a great option for applications that require high-power conversion from AC to DC. It is ideal for applications such as UPS systems, switch-mode power supplies, AC-DC power converters, and other general power rectification applications. The device features four Schottky barrier rectifiers arranged in an H-bridge configuration and is able to efficiently convert AC current to a desired DC voltage, while also providing an accurate and fast temperature protection feature. Its high-quality components also provide a low-loss, high surge power conversion, making it a great choice for any application.
