ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are those values beyond which
the device could be permanently damaged. Absolute
maximum ratings are stress ratings only and functional
device operation is not implied.

Peak Switch Current, I(PEAK) ..................................................... 2A
Average Switch Current, I(AVG) ....................................... 500mA
Junction Temperature ............................................. 150°C
Storage Temperature Range ...................... –65°C to 150°C
Lead Temperature (Soldering 10 sec.) ..................... 260°C
Thermal Resistance (qJA) ..................................... 160°C/W
