DESCRIPTION

The UFB120FA40P 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-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.
