Vishay Intertechnology Inc. has introduced 10 new fast recovery epitaxial diodes (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 Vishay Semiconductors rectifiers are designed to increase the efficiency of AC/DC and DC/DC converters and of hard- and soft-switched or resonant designs.
The devices offer 30% lower reverse recovery losses than the closest competing rectifiers and 48% lower than Source: Vishay Intertechnology Inc.previous-generation FRED Pt solutions, while maintaining low conduction and switching losses. The result is improved light- and full-load efficiency in high speed LLC output rectification stages for electric vehicle (EV)/hybrid electric vehicle (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 reverse recovery charge while H-type rectifiers feature lower forward voltage. RoHS-compliant and halogen-free, the components offer high temperature operation to 175° C.
