The AUIRF7648M2 and AUIRF7669L2 is first automotive grade DirectFET® devices tailored to DC-DC applications, offer low gate charge and on-state resistance (RDS(on)) to help minimize switching and conduction losses in a variety of switching applications. Moreover, the low parasitic inductance offered by the DirectFET® power package results in excellent high frequency switching performance with reduced waveform ringing which in turn helps limit EMI and filter size.
The AUIRF7648M2 features a PCB footprint 54 percent smaller than a DPak while the AUIRF7669L2 features a PCB footprint 60 percent smaller than a D2Pak...

Diodes introduced the first products from its proprietary DIOFET™
process that monolithically integrates a power MOSFET and anti-parallel
Schottky diode into a single die. Used in the low side MOSFET position of
synchronous buck point-of-load (PoL) converters, the DMS3014SSS and
DMS3015SSS improve the efficiency and lower the operating temperature of fast switching PoL converters in high volume computing, telecom and industrial applications.
These devices with typical RDS(ON) ratings of only 10mO and 8.5mO, respectively, at VGS of 10V, minimize the conduction losses traditionally associated with low side MOSFETs. At the same time, the forward voltage of the DIOFET’s integrated Schottky diode is 25% lower than comparable MOSFET/schottky solutions and 48% lower than that of the intrinsic body diode of a typical MOSFET, thereby minimizing switching losses and improving efficiency...
