70CRU04 Vishay High Power Products Ultrafast Rectifier, 2 x 35 A FRED PtTM FEATURES • • • • • • Two common-cathode diodes Ultrafast reverse recovery Ultrasoft reverse recovery current shape Low forward voltage drop Low leakage current Optimized for power conversion: welding and industrial SMPS applications • Up to 175 °C operating junction temperature • Designed and qualified for industrial level Base common cathode 2 TO-218 1 3 Anode 2 Anode 2 1 Common cathode DESCRIPTION The 70CRU04 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.
