Description
The IRF6612PbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packag-
ing 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 techniques. 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 IRF6612PbF 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 converters that power high current loads such as the latest generation of microprocessors. The
IRF6612PbF has been optimized for parameters that are critical in synchronous buck converter’s SyncFET sockets.
