Description
The IRF6611PbF 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 the footprint of a SO-8 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 tech-
niques. 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 IRF6611PbF balances industry leading on-state resistance while minimizing gate charge along with ultra low package inductance to
reduce both conduction and switching losses. The reduced losses make this product ideal for high frequency/high efficiency DC-DC convert-
ers that power high current loads such as the latest generation of microprocessors. The IRF6611PbF has been optimized for parameters that
are critical in synchronous buck converter’s SyncFET sockets.
