DESCRIPTION
The SiC714CD10 is an integrated solution which contains
two PWM-optimized MOSFETs (high side and low side
MOSFETs) and a driver IC. Integrating the driver allows bet-
ter optimization of Power MOSFETs. This minimizes the
losses and provides better performance at higher frequency.
The SiC714CD10 is packed in Vishay Siliconix’s high perfor-
mance PowerPAK MLF 10 x 10 package. Compact copack-
ing of components helps to reduce stray inductance, and
hence increases efficiency.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is
not implied. Exposure to absolute maximum rating/conditions for extended periods may affect device reliability.

Notes:
a. See Reliability Manual for profile. The PowerPAK MLF 10 x 10 is a leadless package. The end of the lead terminal is exposed copper (not
plated) as a result of the singulation process in manufacturing. A solder fillet at the exposed copper tip cannot guaranteed and is not required
to ensure adequate bottom side soldering interconnection.
b. Rework Conditions: manual soldering with a soldering iron is not recommended for leadless components.
c. Junction-to-case thermal impedance represents the effective thermal impedance of all heat carrying leads in parallel and is intended for use
in conjunction with the thermal impedance of the PC board pads to ambient (R
thJA
= R
thJC
+ R
thPCB-A
). It can also be used to estimate chip
temperature if power dissipation and the lead temperature of heat carrying (drain) lead is known.
