600 V and 1200 V Devices Increase Efficiency in Automotive, Solar, and UPS Applications

Vishay Intertechnology, Inc. (NYSE: VSH) today introduced 15 new FRED Pt® Gen 5 600 V and 1200 V Hyperfast and Ultrafast rectifiers in the compact SOT-227 package. Offering the best conduction and switching loss trade-off for devices in their class, the Vishay Semiconductors rectifiers are designed to increase the efficiency of high frequency converters and of soft-switched or resonant designs.

Matched to operate with MOSFETs or high speed IGBTs, the devices released today are optimized for PFC and output rectification stages for EV / HEV battery charging stations, booster stages for solar inverters, and UPS. For these applications, the rectifiers offer lower conduction losses than previous-generation devices while maintaining low reverse recovery losses. In addition, the semiconductor in the SOT-227 package is isolated from the copper base plate, allowing for common heatsinks and compact assemblies to be built.

The devices offer current capability of 30 A at 600 V in the single-phase bridge configuration and 60 A to 300 A at 600 V and 1200 V in the dual-diode configuration. The rectifiers are available in X-type Hyperfast and H-type Ultrafast speed classes, with H-type devices offering the advantage of lower conduction losses and X-type devices featuring faster recovery times. The components offer high temperature operation to +175 °C.
