4 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 so guaranteed when the junction temperature is inside the
(-40 C; +150 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 (please refer to Section 2.2: Thermal data on page 5).
However the embedded thermal protection disables the switching activity to protect the
device in case the junction temperature reaches the T
SHTDWN
(+150 C ± 10 C)
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.
