Best in class hyperfast and ultrafast rectifiers reverse recovery losses

Vishay Intertechnology has released ten new AEC-Q101 qualified FRED Pt Gen 5 600V Hyperfast and Ultrafast rectifiers for automotive applications. 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 provide 30% lower reverse recovery losses than the closest competing rectifiers and 48% lower than previous-generation FRED Pt solutions while sustaining low conduction and switching losses. The result is increased light- and full-load efficiency in high-speed LLC output rectification stages for EV/HEV onboard chargers.

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