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 the Section 8.4 Thermal

considerations).

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 because of self-heating.
