• Up to 175°C Operating Junction Temperature
Description/ Applications
The 70CRU04 integrates two state-of-the-art International Rectifier’s Ultrafast recovery rectifiers in the common-
cathode configuration. The planar structure of the diodes, and the platinum doping life-time control, provide a
Ultrasoft recovery current shape, together with the best overall performance, ruggedness and reliability
characteristics.
These devices are thus intended for high frequency applications in which the switching energy is designed not to be
predominant portion of the total energy, such as in the output rectification stage of Welding machines, SMPS, DC-
DC converters. Their extremely optimized stored charge and low recovery current reduce both over-dissipation in
the switching elements (and snubbers) and EMI/RFI.
