MALVERN, Pa. — April 19, 2019 — Vishay Intertechnology, introduced six new FRED Pt Gen 5 1200 V Hyperfast and Ultrafast rectifiers. Offering the best conduction and switching loss trade-off for devices in their class, the 30 A and 60 A Vishay rectifiers are designed to increase the efficiency of high frequency converters, and hard- and soft-switched or resonant designs.

Matched to operate with MOSFETs or high speed IGBTs, the devices released today are optimized for PFC and output rectification stages for EV / HEV battery charging stations, booster stages for solar inverters, and UPS and welding applications. The rectifiers offer up to 10 % lower losses than competing silicon solutions, cutting the efficiency gap with SiC diodes in half and providing a cost-effective alternative for applications with frequencies in the range of 50 kHz.

Both 30 A and 60 A rectifiers are available in the TO-247L package and in X-type Hyperfast and H-type Ultrafast speed classes. 30 A devices are also offered in the TO-220AC. X-type rectifiers offer the advantage of lower QRR, while H-type devices feature lower forward voltage. Both offer the same forward voltage as competing solutions, while delivering up to 40 % lower switching losses and QRR, respectively. The components offer high temperature operation to +175 °C.
