Description
The IRF6709S2TRPbF 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 techniques, when application note AN-1035 is followed regarding the manufacturing methods and processes. The DirectFET pack-
age allows dual sided cooling to maximize thermal transfer in power systems, improving previous best thermal resistance by 80%.
The IRF6709S2TRPbF has 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 IRF6709S2TRPbF has been optimized for the control FET socket of synchronous buck operating from 12 volt bus
converters.
