Datasheet parameters over the temperature range
100% of the population in the production flow is tested at three different ambient
temperatures (-40 °C, +25 °C, and +125 °C) to guarantee the datasheet parameters inside
the junction temperature range (-40 °C, +125 °C).
The device operation is guaranteed when the junction temperature is inside the (-40 °C;
+150 °C) temperature range. The user can estimate the silicon temperature increase with
respect to the ambient temperature evaluating the internal power losses generated during
device operation (please refer to
However, the embedded thermal protection disables the switching activity to protect the
device in case the junction temperature reaches the T
temperature.
All the datasheet parameters can be guaranteed to a maximum junction temperature of
+125 °C, to avoid triggering the thermal shutdown protection during the testing phase due to
self heating.
