DESCRIPTION

The UFB120FA20P 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/DC converters. Their extremely optimized stored charge

and low recovery current reduce both over dissipation in the

switching elements (and snubbers) and EMI/RFI.
