DESCRIPTION
The UFB120FA20P insulated modules integrate two state of
the art Vishay HPP 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-to-dc converters. Their extremely optimized stored
charge and low recovery current reduce both over
dissipation in the switching elements (and snubbers) and
EMI/RFI.

Formula used: TC = TJ - (Pd + PdREV) x RthJC
;
Pd = Forward power loss = IF(AV) x VFM at (IF(AV)/D) (see fig. 6);
PdREV = Inverse power loss = VR1 x IR (1 - D); IR at VR1 = 80 % rated VR
