CAUTION: Stresses 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 sections of this specification is not implied.

+150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Constantly operated at +150°C may shorten the life of the part.

NOTES:

1. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Technical Brief TB379 for details.

2. All voltages are with respect to GND.
