Datasheet parameters over the temperature range
The 100% of the population in the production flow is tested at three different ambient
temperatures (-40 °C, +25 °C, +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,
+125 °C) temperature range. The designer can estimate the silicon temperature increase
respect to the ambient temperature evaluating the internal power losses generated during
the device operation.
However the embedded thermal protection disables the switching activity to protect the
device in case the junction temperature reaches the TSHDN (+150 °C typ.) 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
because of self-heating.
