DESCRIPTION
The 70CRU02 integrates two state of the art Vishay HPP
ultrafast recovery rectifiers in the common-cathode
configuration. 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.

Note
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 = Rated VR
