Abstract

This paper presents experimental robustness of 600 V GaN High Electron Mobility Transistors (HEMT) submitted to Short-Circuits (SC) operation modes. A dedicated secured test bench has been developed and designed in order to protect as quickly as possible the Device Under Test (DUT) after failure. Some devices featured a great robustness under SC and were able to support several SC of a very long duration. On the contrary, others failed immediately at the first pulse, for a low dissipated energy. The obtained results reveal a severe dispersal in terms of SC robustness for these new emerging components. Gate behavior has been also studied, showing a leakage current during each SC, destructive or not. A part of the paper is also dedicated to the study of the effects of case temperature and DC voltage on robustness.
