Description
The IRF6603 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 an 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 process. The DirectFET package
allows dual sided cooling to maximize thermal transfer in power systems, IMPROVING previous best thermal resistance by 80%.
The IRF6603 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 IRF6603 has been optimized for parameters that are critical in synchronous buck
converters including Rds(on), gate charge and Cdv/dt-induced turn on immunity. The IRF6603 offers particularly low Rds(on) and high Cdv/
dt immunity for synchronous FET applications.
