DESCRIPTION
The VS-70CRU04PbF integrates two state of the art Vishay
Semiconductors 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.
