MALVERN, Pa. — Vishay Intertechnology today 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 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 released today offer 30 % lower reverse recovery losses than the closest competing rectifiers and 48 % lower than 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 EV / 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.
