Vishay’s New Rectifiers Reduces Conduction and Switching Losses

Hyperfast and Ultrafast

Vishay Intertechnology has added six new FRED Pt Gen 5 1200 V Hyperfast and Ultrafast rectifiers. The company said that the recently launched rectifiers offer 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 of hard- and soft-switched or resonant designs.

The Major Application of the Devices Include:

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 do 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.
