Vishay Intertechnology has introduced 10 new FRED Pt Gen 5 600V Ultrafast rectifiers that offer reverse recovery performance for devices and are designed to increase the efficiency of AC/DC and DC/DC converters and of hard- and soft-switched or resonant designs. This device is specifically designed to improve the efficiency of high-speed LLC output rectification stages of EV / HEV battery charging stations and high-frequency stages of UPS applications.


These 15A, 30A, 60A, and 75A rectifiers 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. These 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. 



  • Best in class forward voltage drop and switching losses trade-off

  • Optimized for high-speed operation

  • 175°C maximum operating junction temperature



  • AC/DC and DC/DC converters

  • EV / HEV battery charging stations

  • UPS applications



Samples and production quantities of the new FRED Pt rectifiers are now available with lead times of 12 weeks.
