| 70CRU02PBF Vishay High Power Products Ultrafast Rectifier, 2 x 35 A FRED PtTM FEATURES Base common cathode 2 * * * * * * TO-218 1 3 Anode 2 Anode 2 1 Common cathode Two common-cathode diodes Available Ultrafast reverse recovery Ultrafast reverse recovery current shape RoHS* COMPLIANT Low forward voltage drop Low leakage current Optimized for power conversion: welding and industrial SMPS applications * Up to 175 C operating junction temperature * Lead (Pb)-free ("PbF" suffix) * Designed and qualified for industrial level 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.
