Datasheet

Vishay introduces a new series of enhanced high-current-density PowerBridge rectifiers with current ratings of 30 A to 45 A, maximum peak reverse voltage ratings of 600 V to 1000 V, and a high case dielectric strength of 1500 V. The series’ 45-A devices are the industry’s first single in-line bridge rectifiers in the PowerBridge package, which features a body size of 30 mm by 20 mm with a 3.8-mm profile.

Compared to larger-size bridge rectifiers on the market, the advanced thermal construction of the PowerBridge devices allows heat to dissipate more efficiently. The PowerBridge rectifiers are thus able to provide the same power ratings as larger packages while requiring smaller heat sinks.

The single in-line rectifiers are the ideal choice for ac-to-dc rectification in switchmode power supplies for desktop PCs, servers, PDP TVs, LCD TVs, audio/video systems; power inverters in home appliances such as refrigerators, washing machines, air conditioners, and induction cookers; and primary rectification circuits for switchmode power supplies in telecommunication systems.

For OEM vendors, the new devices offer compatible package, lead pitch, and pin layouts to the conventional GSIB-5S package. This saves time by allowing the same PCB layout to be used for a wide range of bridge rectifier voltage and current ratings. The rectifiers’ + 275 °C, 10-second solder dipping process per JESD 22-B106 enables high reliability in wave soldering or manual soldering.
