New Yorker Electronics has released 12 new FRED Pt Gen 5 1200V Hyperfast and Ultrafast rectifiers from Vishay Semiconductor. An excellent choice for soft switched and resonant high-frequency converters, it provides a unique combination of low conduction and switching losses. Specially created to enhance the efficiency of PFC and output rectification stages of EV/HEV battery charge stations, booster stage of solar inverters and UPS applications, these devices are ideally matched to operate with MOSFETs or high-speed IGBTs.
The 12 new rectifiers provide the best conduction and switching loss trade-off for devices in their class. Ranging from 8A up to 60A, in single and dual-diode configurations, the rectifiers are created to improve the efficiency of high-frequency converters and hard and soft-switched or resonant designs.
Matched to operate with MOSFETs or high-speed IGBTs, they supply up to 10% lower losses than competing silicon solutions. They can cut the efficiency gap with SiC diodes in half and deliver a cost-effective alternative for applications with frequencies in the range of 50kHz.
The new devices provide the same forward voltage as competing solutions while delivering up to 40% lower switching losses and QRR. The case moulding compound meets UL 94 V-0 flammability rating, and its terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102,
Typical applications include three-phase t-type PFC and output rectification stages for EV/HEV battery charging stations; booster stages for solar inverters, UPS, and welding.
