DESCRIPTION

The UFB200FA40P 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.
