"The IRF7853PbF is designed for AC-DC secondary-side synchronous rectification, isolated medium-power DC-DC applications.

The 100V IRF7853 is also optimized for wide-range communication bus input (36V to 75V) primary-side bridge topologies in isolated DC-DC bus converters. The 80V IRF7854 is useful for active ORing and hot-swap applications. All three of the MOSFETs are designed for secondary-side synchronous rectification in 5-19Vout flyback converter and resonant half-bridge applications and are suitable for isolated DC-DC applications as primary-side switches in forward or push-pull topologies for 18-36Vin isolated DC-DC converters.

Together with IRs low-voltage MOSFETs and controller ICs, these mid-range MOSFETs form secondary-side chipsets for medium-power, converter applications. In addition, when combined with the SmartRectifierTM IR1167 in AC-DC power supplies such as laptop adaptors, for example, these new SO-8 devices can replace two of their large TO-220 MOSFET counterparts and their associated heatsinks, improving overall system efficiency by as much as 1%.
