The suitability of these TSEPs for the junction temperature estimation in power cycling (PC) tests is evaluated. The findings can serve as a guide for choosing the most suitable TSEPs for a universal PC test bench for both GaN and SiC devices.enGallium nitridePower cyclingSilicon carbideTemperature sensitive electrical parameterWide-bandgapconference paper
