DESCRIPTION
The VS-UFB280FA40 insulated modules integrate two state
of the art ultrafast recovery rectifiers in the compact,
industry standard SOT-227 package. The diodes structure,
and its life time control, provide an 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.
