## **Description** 

The IRF6811STRPbF combines the latest HEXFET[®] Power MOSFET Silicon technology with the advanced DirectFET[®] packaging to achieve improved performance in a package that has the footprint of a MICRO-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 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 IRF6811STRPbF has low gate resistance and low charge along with ultra low package inductance providing significant reduction in switching losses. The reduced losses make this product ideal for high efficiency DC-DC converters that power the latest generation of processors operating at higher frequencies.  The IRF6811STRPbF has been optimized for the control FET socket of synchronous buck operating from 12 volt bus converters.
