Reliability of a GaN-based Hybrid-Drain-embedded Gate Injection Transistor (HD-GIT) under continuous switching operation is investigated to extract the lifetime under a practical switching application. Switching lifetimes are deduced by varying ambient temperature, switching voltage and switching current to obtain their corresponding acceleration factors. Based on the obtained factors, we determine Switching Safe Operating Area (SSOA) that is proposed recently to define the I

area inside which the device can be switched safely. To our knowledge, this is the first demonstration of SSOA for a GaN power transistor. We estimate the switching lifetime when the HD-GITs are employed in 3 kW totem-pole power factor correction (PFC) circuit under a typical usage condition. The estimated lifetime is 24 years, which we believe is sufficiently long. |
