1 / 9 page  www.irf.com 1 11/14/07 DirectFET Power MOSFET DirectFET ISOMETRIC MZ PD - 97262A Applicable DirectFET Outline and Substrate Outline (see p.7,8 for details) Fig 1. Typical On-Resistance vs. Gate Voltage Typical values (unless otherwise specified) Description The IRF6641PbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packaging 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, 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 IRF6641PbF is optimized for primary side sockets in forward and push-pull isolated DC-DC topologies, for wide range 36V- 75V input voltage range systems. The reduced total losses in the device coupled with the high level of thermal performance enables high efficiency and low temperatures, which are key for system reliability improvements, and makes this device ideal for high performance isolated DC-DC converters.
