2.1 SEL Test

A thermistor was attached to the DUT board up against the DUT to monitor the temperature. The DUT was heated with a heat gun so that the thermistor read at least 125°C. Based on the power dissipation of the DUT and the thermal modeling of the ceramic package, the junction temperature is approximately 20°C higher than the thermistor reading.

The supply current was monitored on a display in real time and also recorded by the PXI controller.
