Description
The IRF6623 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 MICRO-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 manufac-
turing 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 IRF6623 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 IRF6623 has been optimized for parameters that are
critical in synchronous buck operating from 12 volt buss converters including Rds(on) and gate charge to minimize losses in
the control FET socket.
