Description
The IRF6720S2PbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM 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 tech-
niques, 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 IRF6720S2PbF 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 IRF6720S2PbF has been optimized for the control FET socket of synchronous buck oper-
ating from 12 volt bus converters.
