VISHAY'S NEW 8-A, 600-V ULTRAFAST RECTIFIERS OFFER 25-NS REVERSE RECOVERY AND 150-NS FORWARD RECOVERY
27 November 2006 - Vishay Electronic

Vishay Intertechnology, Inc. is adding to its portfolio of high-voltage Ultrafast rectifiers with a pair of new devices that reduce power losses in the switchmode power supplies for consumer, computer, and industrial products with their extremely fast reverse and forward recovery times and low forward voltage drop.

The new 8-A, 600-V UH8JT and UHF8JT single high-voltage Ultrafast rectifiers deliver a reverse recovery time of 25 ns. This improved switching performance combines 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, to enable better thermal performance and better system efficiency.

Built using an planar chip junction technology, the UH8JT and UHF8JT will be used for a range of power supply applications, including high-voltage continuous-current-mode power factor correction 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 degrees Celsius and are compliant with ROHS 2002/95/EC and WEEE 2002/96/EC.

Samples and production quantities of the new devices are available now, with lead times of four to eight weeks for larger orders.
