New hyperfast and ultrafast rectifiers offer best in class reverse recovery losses

Vishay Intertechnology has launched ten new FRED Pt Gen 5 600V Hyperfast and Ultrafast rectifiers. Providing the best reverse recovery performance for devices in their class, the 15A, 30A, 60A, and 75A Vishay Semiconductors rectifiers are created to improve the efficiency of AC/DC and DC-DC converters and of hard- and soft-switched or resonant designs.

The devices claim 30% lower reverse recovery losses than the nearest competing rectifiers and 48% lower than past-generation FRED Pt solutions while maintaining low conduction and switching losses. The result is increased light and full-load efficiency in high-speed LLC output rectification stages for EV/HEV battery charging stations and high-frequency stages for UPS applications.

The rectifiers are offered in TO-220AC and TO-247AD packages and X-type Hyperfast and H-type Ultrafast speed classes. X-type devices provide the advantage of lower QRR, while H-type rectifiers give lower forward voltage. RoHS-compliant and halogen-free, the components provide high-temperature operation to +175C.
