This release in:

MALVERN, PENNSYLVANIA. — September 2, 2009 — Vishay Intertechnology, Inc. (NYSE: VSH) today 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 extremely fast reverse recovery time, low forward voltage drop, and low package thermal resistance.

The new 8S2TH06I-M is optimized 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.

A unique balance of conduction and switching performance improvements allows the 8S2TH06I-M to provide an average overall power loss reduction of 22 % in typical high-frequency PFC applications.

Delivering a reverse recovery time of 11 ns, the 8S2TH06I-M combines its Hyperfast switching performance with a low forward voltage drop rating of 2.1 V at 8 A, allowing the device to work at higher frequencies to increase overall system efficiency. Its 2-pin TO-220 package enables the device to provide 8 A DC 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, yet with minimum effect on its benchmark 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, which represents a significant improvement in the tradeoff between Qrr and forward voltage drop. The result is the ability to combine high-frequency operation with lower losses, allowing heat sinks and passive components to be downsized. Likewise, the 8S2TH06I-M’s operating junction temperature of 175 C allows for more robust and more cost effective designs, and represents a 15 % improvement over competing devices, for which 150 C is the maximum rating.

Device Specification Table:

Device number 8S2TH06I-M
IF(AV) 8 A
@ TC 120 C
VF @ 125 C (Typ.) 2.1 at 8 A
Qrr @ 125 C at rated IF − 200 A/us at 390 V 35 nC
