Vishay Intertechnology introduces FRED Pt Gen 5 rectifiers

Offering high conduction and switching loss trade-off for devices, 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 are optimised 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 30A at 600V in the single-phase bridge configuration and 60A to 300A at 600V and 1200V 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.
