kr VS-UFB280FA40 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 SOT-227 • Optimized for power conversion: welding and industrial SMPS applications • Easy to use and parallel • Industry standard outline • Compliant to RoHS Directive 2002/95/EC • Designed and qualified for industrial level DESCRIPTION PRODUCT SUMMARY VR IF(AV) per module at TC = 90 °C trr Type 400 V 280 A 40 ns Modules - Diode FRED Pt® The VS-UFB280FA40 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.

400 170 1300 395 2500 - 55 to 175 UNITS V A W V °C Note (1) Maximum continuous forward current must be limited to 100 A to do not exceed the maximum temperature of power terminals.
