Vishay has launched a new 600 V FRED Pt Hyperfast tandem rectifier that reduces losses in high-efficiency continuous current mode (CCM) power factor correction (PFC) applications with its fast reverse recovery time, low forward voltage drop and low package thermal resistance. The new 8S2TH06I-M is designed for use in desktop PCs, server and telecom power supplies, UPS systems, wide-screen plasma display and LCD power supplies, industrial power supplies and solar inverters.
Delivering a reverse recovery time of 11 ns, the device combines its Hyperfast switching performance with a low forward voltage drop rating of 2,1 V at 8 A, allowing it to work at high frequencies to increase overall system efficiency. Its 2-pin TO-220 package enables it to provide 8 A d.c. at a 120°C case temperature while delivering insulation exceeding 2 kV. The ceramic-insulated TO-220 package is designed for easy mounting together with non-insulated parts, and features a thermal resistance of 2,3°C/W junction to case. Reverse recovery charge for the 8S2TH06I-M is 7 nC at 25°C and 35 nC at 125°C.
