jc = 13.5°C/W

Notes:

1. Operation of this device in excess of any of

these limits may cause permanent damage.

2. Thermal resistance measured using Infra-

Red Measurement Technique.

3. Board temperature (Tc) is 25° C. For Tc

>55.5° C, derate the device power at 74.1 mW

per °C rise in board temperature adjacent to

package bottom.
