Description
The IRF6620 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 tech-
niques, 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 IRF6620 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 IRF6620 has been optimized for parameters that are critical in synchronous buck operating from 12 volt
buss converters including Rds(on), gate charge and Cdv/dt-induced turn on immunity. The IRF6620 offers particularly low Rds(on) and high
Cdv/dt immunity for synchronous FET applications.
