DESCRIPTION
The VS-UFB310CB40 not insulated modules integrate two
state of the art ultrafast recovery rectifiers in the compact,
industry standard SOT-227 package. 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.
