MALVERN, PA — September 13, 2022 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced the availability of 15 new FRED Pt® Gen 5 600 V and 1200 V Hyperfast in a small SOT-227 package and Ultrafast recovery rectifier. Vishay Semiconductors rectifier conduction and switching losses are state-of-the-art in their class, improving the efficiency of high-frequency inverters and soft-switching or resonant circuits.
The recently released devices can be used with MOSFETs or high-speed IGBTs for PFC, electric (EV) / hy brid electric vehicle (HEV) battery charging station output rectifier stage, solar inverter booster stage and UPS, where the rectifier conduction loss is lower than the previous generation of devices, while the reverse recovery loss is low. In addition, the SOT-227 package semiconductor devices are insulated from the copper substrate, making it easy to build universal heat sinks and small assemblies.
The 30 A / 600 V devices are available in a single-phase bridge configuration and the 60 A - 300 A / 600 V - 1200 V devices are available in a dual diode configuration. The rectifiers are available in two speed types, X-type Hyperfast and H-type Ultrafast. H-type rectifiers have the advantage of low conduction loss, while X-type rectifiers have the advantage of fast recovery. The devices operate at temperatures up to +175 °C.
