UFL120FA60P Vishay High Power Products Insulated Ultrafast Rectifier Module, 120 A FEATURES • Two fully independent diodes • Ceramic fully insulated package (VISOL = 2500 VAC) RoHS COMPLIANT • Ultrafast reverse recovery • Ultrasoft reverse recovery current shape • Low forward voltage 1 • Optimized for power conversion: welding and industrial SMPS applications 4 • Industry standard outline • Plug-in compatible with other SOT-227 packages • Easy to assemble 2 • Direct mounting to heatsink 3 • Totally lead (Pb)-free SOT-227 • Designed and qualified for industrial level DESCRIPTION The UFL120FA60P insulated modules integrate two state of the art Vishay’s 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 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 a predominant portion of the total energy, such as in the output rectification stage of welding machines, SMPS, and 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.
