DESCRIPTION
The UFB60FA20P insulated modules integrate two state of
the art Vishay Semiconductors 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-to-dc converters. Their extremely optimized stored
charge and low recovery current reduce both over
dissipation in the switching elements (and snubbers) and
EMI/RFI.
