| UFB120FA40P Vishay High Power Products Insulated Ultrafast Rectifier Module, 120 A FEATURES * Two fully independent diodes * Ceramic fully insulated package (VISOL = 2500 VAC) * Ultrafast reverse recovery * Ultrasoft reverse recovery current shape * Low forward voltage * Optimized for power conversion: welding and industrial SMPS applications 4 RoHS COMPLIANT SOT-227 1 * Industry standard outline * Plug-in compatible with other SOT-227 packages * Easy to assemble * Direct mounting to heatsink * Lead (Pb)-free * Designed and qualified for industrial level 2 3 DESCRIPTION The UFB120FA40P insulated modules integrate two state of the art 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.
