Malvern, Pa. Vishay Intertechnology, Inc. beefs up its portfolio of high-voltage ultra-fast rectifiers with two devices that reduce power losses in switchmode power supplies for consumer, computer, and industrial products with extremely fast reverse and forward recovery times and a low forward voltage drop.
The 8-A, 600-V UH8JT and UHF8JT single high-voltage ultra-fast rectifiers deliver improved switching performance with a reverse recovery time of 25 ns. When combined with a forward recovery time of 150 ns under LEM test conditions (IF = 8 A, di/dt = 64 A/microsecond, VF = 1.1 x VF max), and a low forward voltage drop rating of 1.85 V at 125°C, these devices enable enhanced thermal performance and system efficiency.
Built using a planar chip junction technology, the UH8JT and UHF8JT may be used for a range of power supply applications including high-voltage continuous-current-mode power factor correction (CCM PFC) systems in consumer and computer products; high-voltage output switchmode power supplies; secondary dc-to-dc rectification applications and freewheeling diode applications.
The UH8JT (TO-220AC) and UHF8JT (ITO-220AC) feature a maximum junction temperature of 175°C and are compliant with European Union's Restriction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) directives.
Pricing for U.S. delivery is $0.35 each in quantities of 10,000. Samples and production quantities of the UH8JT (TO-220AC) and UHF8JT (ITO-220AC) devices are available now, with lead times of four to eight weeks for larger orders.
