Vishay Introduces New Gen 5 FRED Pt Gen 5 600 V Ultrafast Rectifiers

Vishay Intertechnology

MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) this week 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 devices released today 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-VS5HD240CW60, VS-VS5HD300CW60, VS-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.

Device Specification Table:

Part number VR (V) IF(AV) (A) Qrr typical (nC) trr (ns) Package
VS-VS5HD240CW60 600 240 at 95 °C 260 52 TO-244
VS-VS5HD300CW60 600 300 at 81 °C 620 68 TO-244
VS-VS5HD480CW60 600 480 at 92 °C 525 61 TO-244
VS-VS5HD600CW60 600 600 at 77 °C 800 78 TO-244
