Abstract

In this paper, the short-circuit robustness of a normally off GaN HEMT is investigated in relation to applied bias conditions and pulse duration. The results align with previous studies on normally-on devices in highlighting an electrical type of failure. Here, however, the relevance of the specific gate-drive circuit design and corresponding device operational condtions is demonstrated. A gate-bias dependence (GBD) of the failure, correlated to the applied drain-source voltage, is introduced as a novel specific feature for the p-Gate type device.
