Single high-voltage ultrafast rectifiers

The new 8A 600V UH8JT and UHF8JT single high-voltage ultrafast rectifiers from Vishay Intertechnology Inc. deliver a reverse recovery time of 25ns. According to the company, this improved switching performance combines with a forward recovery time of 150ns under LEM test conditions (IF = 8A, di/dt = 64A/s, VF = 1.1 x VF max), and a low forward voltage drop rating of 1.85V at 125C to boost thermal performance and system efficiency.

The planar devices, suited for switchmode power supplies, including high-voltage continuous-current-mode power factor correction (CCM PFC) applications, are rated for a maximum junction temperature of 175C. They are compliant with ROHS 2002/95/EC and WEEE 2002/96/EC specifications.

Samples and production quantities are available now, with lead times of four to eight weeks for larger orders. Pricing for U.S. delivery in 10,000-piece quantities is 35 cents per piece.
