VSKC270-12 Application field and Working Principle

Introduction

VSKC270-12 is a range of three phase rectifier diodes developed by Vishay Semiconductor. The range of diodes is constructed from vapour phase soldered SOD-523 package, with the back side connected to a common cathode. The range of VSKC270-12s has been further improved for increased efficiency and is capable of full-wave rectification with a low forward voltage drop.

Application Field

VSKC270-12 can be used in a wide variety of applications including ac/dc conversion, dc servo motor control, and variable frequency drives. The wide availability of the SOD-523 package makes it ideal for use in several different industry applications.In particular, the VSKC270-12 range of diodes is ideal for use in applications involving the ac/dc conversion of household appliances such as rice cookers, cameras, printers, TVs and mobile phones. The diode range is also suitable for applications in the telecommunications and automotive industries.

Working Principle

The VSKC270-12 range of diodes works by rectifying alternating current (AC) into direct current (DC). The AC supply is converted into DC by passing it through the rectifier, which passes the positive half of the waveform, but blocks the negative half.The rectifier is made up of a series of diodes wired in a configuration known as a bridge rectifier. This configuration utilises two pairs of inverted diodes connected in a series back-to-back configuration. It works by having each end of the AC input (the anode and cathode) connected to the order of the diodes with the opposites connected to each other.The bridge rectifier is then used to pass the incoming AC current through the diodes, where the positive half the waveform is passed through and the negative half is blocked. This process then creates DC voltage at the output.In addition to the rectifying process, the VSKC270-12 range of diodes also offers a low forward voltage drop and excellent thermal stability, making them ideal for use in applications that require a high level of efficiency and reliability.

Conclusion

The VSKC270-12 range of diodes are a highly versatile range of rectifier diodes, capable of full-wave rectification with a low forward voltage drop. They are suitable for use in a wide variety of applications, ranging from ac/dc conversion to variable frequency drives, and are especially suited to applications which require a high level of efficiency and reliability.
