Bulletin PD-20488 12/01 UFB120FA40 Insulated Ultrafast Rectifier Module Features * * * * * * * * * * Two Fully Independent Diodes Ceramic Fully Insulated Package (VISOL = 2500V AC) Ultrafast Reverse Recovery Ultrasoft Reverse Recovery Current Shape Low Forward Voltage Optimized for Power Conversion: Welding and Industrial SMPS Applications Industry Standard Outline Plug-in Compatible with other SOT-227 Packages Easy to Assemble Direct Mounting to Heatsink trr = 35ns IF(AV) = 120A @ TC = 65C VR = 400V Description The UFB120FA40 insulated modules integrate two state-of-the-art International Rectifier's Ultrafast recovery rectifiers in the compact, industry standard SOT-227 package. The planar structure of the diodes, and the platinum doping lifetime 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, DCDC converters. Their extremely optimized stored charge and low recovery current reduce both over dissipation in the switching elements (and snubbers) and EMI/ RFI.
