The Vishay KBU series single-phase bridge rectifiers are designed for general-purpose AC/DC full-wave rectification. They are ideal for printed circuit boards and offer high surge current capability and high case dielectric strength. Applications include monitors, TVs, printers, SMPS, adapters, audio equipment, and home appliances.
