Description
The IRF6638PbF 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 0.6 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 IRF6638PbF balances both low resistance and low charge along with ultra low package inductance to reduce both conduction and
switching losses. The reduced total losses make this product ideal for high efficiency DC-DC converters that power the latest generation of
processors operating at higher frequencies. The IRF6638PbF has been optimized for parameters that are critical in synchronous buck
including Rds(on), gate charge and Cdv/dt-induced turn on immunity. The IRF6638PbF offers particularly low Rds(on) and high Cdv/dt
immunity for synchronous FET applications.
