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 Section 2.2).

However, the embedded thermal protection disables the switching activity to protect the

device in case the junction temperature reaches the TSHTDWN (+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 due to

self-heating.
