Absolute maximum ratings
This part may be irreparably damaged if taken outside the specified Absolute Maximum Ratings. Operation above
the Absolute Maximum Ratings may also cause a decrease in reliability.
The operating junction temperature range is -40 °C to +150 °C. The maximum junction temperature must not be
exceeded except when in deployment and within the deploy power stages. Deployment is possible starting with a
junction temperature of 150 °C.
