Description
The IRF7779L2TR/TR1PbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packaging to
achieve the lowest on-state resistance in a package that has a footprint smaller than a D2PAK and only 0.7 mm profile. The DirectFET package is
compatible with existing layout geometries used in power applications, PCB assembly equipment and vapor phase, infra-red or convection soldering
techniques, when application note AN-1035 is followed regarding the manufacturing methods and processes. The DirectFET package allows dual
sided cooling to maximize thermal transfer in power systems.
The IRF7779L2TR/TR1PbF is optimized for high frequency switching and synchronous rectification applications. The reduced total losses in
the device coupled with the high level of thermal performance enables high efficiency and low temperatures, which are key for system reliability
improvements, and makes this device ideal for high performance power converters.
