Vishay FRED Pt Gen 5 Ultrafast Rectifiers in TO-244 Package

Offering High Speed, High Temperature Operation, 240 A to 600 A Devices Increase Efficiency in Industrial Applications


MALVERN, Pa.— Vishay Intertechnology has introduced four new FRED Pt Gen 5 600 V Ultrafast rectifiers in the TO-244 package. Offering the best conduction and switching loss trade-off for devices in their class, the 240 A, 300 A, 480 A, and 600 A Vishay Semiconductors rectifiers are designed to increase the efficiency of medium frequency power converters and of hard- and soft-switched or resonant designs.

Compared to competing FRED Pt Ultrafast solutions in the TO-244 package, the new Vishay Ultrafast Rectifiers offer lower conduction while maintaining low reverse recovery losses. The result is improved efficiency for industrial applications, such as high-frequency welding and ballast water management systems. Delivering high-speed, high-temperature operation for these applications, the VS-VS5HD240CW60VS-VS5HD300CW60VS-VS5HD480CW60, and VS-VS5HD600CW60 offer low Qrr down to 260 nC typical, fast recovery time down to 52 ns, and an operating temperature range up to +175 °C.
