PD - 96977B IRF6636 DirectFETTM Power MOSFET Typical values (unless otherwise specified) RoHS compliant containing no lead or bromide VDSS VGS RDS(on) RDS(on) Low Profile (<0.7 mm) 20V max 20V max 3.2m@ 10V 4.6m@ 4.5V Dual Sided Cooling Compatible Qg tot Qgd Qgs2 Qrr Qoss Vgs(th) Ultra Low Package Inductance 18nC 6.1nC 1.9nC 7.3nC 10nC 1.8V Optimized for High Frequency Switching Ideal for CPU Core DC-DC Converters Optimized for for Control FET socket of Sync. Buck Converter Low Conduction and Switching Losses Compatible with existing Surface Mount Techniques ST Applicable DirectFET Outline and Substrate Outline (see p.7,8 for details) SQ SX ST MQ MX MT DirectFETTM ISOMETRIC Description The IRF6636 combines the latest HEXFET(R) 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 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 IRF6636 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 IRF6636 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.
