Description  
The IRF6655PbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packaging to achieve the  
lowest combined on-state resistance and gate charge in a package that has a footprint similar to that of a micro-8, and only 0.7mm 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, improving previous best thermal resistance by  
80%.  
The IRF6655PbF is optimized for low power primary side bridge topologies in isolated DC-DC applications, and for high side control FET sockets  
in non-isolated synchronous buck DC-DC applications for use in wide range universal Telecom systems (36V – 75V), and for secondary side  
synchronous rectification in regulated DC-DC topologies. The reduced total losses in the device coupled with the high level of thermal perfor-  
mance enables high efficiency and low temperatures, which are key for system reliability improvements, and makes this device ideal for high  
performance isolated DC-DC converters.
