Vishay Intertechnology, Inc. has introduced 10 new FRED Pt Gen 5 600 V Hyperfast and Ultrafast rectifiers — offering the best reverse recovery performance for devices in their class. The 15 A, 30 A, 60 A, and 75 A rectifiers are designed to increase the efficiency of AC/DC and DC/DC converters and of hard and soft-switched or resonant designs.
The new products offer 30 percent lower reverse recovery losses than the closest competing rectifiers and 48 percent lower than previous-generation FRED Pt solutions. This is, while maintaining low conduction and switching losses.
The result: improved light and full-load efficiency in high speed LLC output rectification stages for EV and HEV battery-charging stations and high-frequency stages for UPS applications.
The rectifiers are available in TO-220AC and TO-247AD packages and X-type Hyperfast and H-type Ultrafast speed classes. X-type devices offer the advantage of lower QRR, while H-type rectifiers feature lower forward voltage. RoHS-compliant and halogen-free, the components offer high temperature operation to +175° C.
