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/DC converters. Their extremely optimized stored

charge and low recovery current reduce both over

dissipation in the switching elements (and snubbers) and

EMI/RFI.
