DESCRIPTION / APPLICATIONS

The VS-UFB310CB40 not 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.
