Abstract:
Several tests have been performed to analyze the reliability of GaN GITs soldered on printed circuit boards, including a high temperature gate bias test, a high temperature reverse bias test, a high voltage high humidity high temperature reverse bias test and a power cycling test. Furthermore, four temperature-sensitive electrical parameters have been compared with the results of the power cycling tests for the RDS(on)-method. Finally, a failure analysis has been performed for specimens which have reached end of life in the power cycling test.
