DESCRIPTION / APPLICATIONS

The VS-UFH280FA30 insulated modules integrate two state

of the art ultrafast recovery rectifiers in the compact,

industry standard SOT-227 package. The diodes structure,

and its life time control, provide an 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.
