Description
The IRF7748L1TRPbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packag-
ing 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 IRF7748L1TRPbF 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 sys-
tem reliability improvements, and makes this device ideal for high performance power converters.
