Description

The IRF6729MPbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFET

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 IRF6729MPbF balances industry leading on-state resistance while minimizing gate charge along with ultra low package inductance to

reduce both conduction and switching losses. This part contains an integrated Schottky diode to reduce the Qrr of the body drain diode further

reducing the losses in a Synchronous Buck circuit. 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 IRF6729MPbF has been optimized for

parameters that are critical in synchronous buck converter’s Sync FET sockets.
