CAUTION: Stress above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational section of this specification is not implied.
+150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Operation close to +150°C junction may trigger the shutdown of
the device even before +150°C, since this number is specified as typical.
1. θ is measured with the component mounted on a highly effective thermal conductivity test board on free air. See Tech Brief TB379 for details.

2. For θ , the “case temp” location is the center of the exposed metal pad on the package underside.
