Notes:

1. Both power switches each dissipating half the total power.

2. Mounted to an aluminum heat sink with uniform coverage of

Thermalloy thermal paste. Mounting clip with normal force

>30 N applied to the center of the package.

3. Junction to case thermal resistance is based on hottest

junction, case temperature measured at center of package

back surface.

4. Temperature difference between hottest junction and over-

temperature sensor.

5. Thermal resistance values are preliminary and subject to change.
