Description
The UFB200FA40 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.

Pd = Forward Power Loss = IF(AV) x VFM @ (IF(AV) / D) (see Fig. 6);
PdREV = Inverse Power Loss = VR1 x IR (1 - D); IR @ VR1 = 80% rated VR
