VS-UFB280FA20 www.vishay.com Vishay Semiconductors Insulated Ultrafast Rectifier Module, 280 A FEATURES • Two fully independent diodes • Fully insulated package • Ultrafast, soft reverse recovery, with high operation junction temperature (TJ max. = 175 °C) • Low forward voltage drop • Optimized for power conversion: welding and industrial SMPS applications • Easy to use and parallel SOT-227 • Industry standard outline • UL approved file E78996 • Designed and qualified for industrial level • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 DESCRIPTION / APPLICATIONS PRODUCT SUMMARY VR 200 V IF(AV) per module at TC = 100 °C 280 A trr 45 ns Type Modules - Diode FRED Pt® Package SOT-227 The VS-UFB280FA20 insulated modules integrate two state of the art ultrafast recovery rectifiers in the compact, industry standard SOT-227 package. The diodes structure, and its life time control, provide an 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.
