ON Semiconductor KBU8K Bridge Rectifier

The KBU8K is a single-phase bridge rectifier from ON Semiconductor, renowned for its high efficiency and reliability in converting alternating current (AC) to direct current (DC). This electronic component is specifically designed for general-purpose AC-to-DC bridge rectification applications where a compact size and efficient operation are crucial.

Encased in a robust KBU package, the KBU8K bridge rectifier has a peak reverse voltage (PRV) of 800 volts, making it suitable for use in a wide range of electronic circuits that require a high-voltage operation. The device is capable of handling a high average rectified forward current of 8 amperes, with an impressive surge overload rating of 200 amperes, ensuring it can withstand transient overcurrent conditions without damage.

The low forward voltage drop characteristic of the KBU8K ensures that power loss is minimized during the rectification process, which enhances the overall efficiency of the system it is integrated into. Additionally, its high surge current capability provides a margin of safety for applications subject to occasional surges, such as power supplies, adapters, and on-board DC/DC converters.

ON Semiconductor has designed the KBU8K with a high-temperature soldering guaranteed at 260°C for 10 seconds, which allows for a reliable solder joint in the PCB assembly process. Furthermore, the rectifier's terminals are plated with lead-free solder, complying with the RoHS directive, which makes it an environmentally friendly choice for manufacturers looking to reduce hazardous substances in their products.

The KBU8K bridge rectifier is also characterized by its isolation voltage of 2500 volts from case to leads, providing additional protection against electrical shocks and ensuring the safety of end-users. With its glass passivated chip junction, the device offers enhanced reliability and a long operational life, making it an ideal choice for designers and engineers seeking a dependable rectification solution.

In summary, the ON Semiconductor KBU8K bridge rectifier is a high-performance, efficient, and reliable component suitable for a variety of applications that require robust voltage rectification capabilities.
