Abstract
The COTS power transistors based in GaN were exposed to TID effects by 10-keV X-rays. These HEMTs were tested in the On- and Off-state bias-condition. Switching tests were performed before, during and after irradiation. The devices were characterized at temperatures ranging from −50°C to +75°C. The results indicate that the GaN-technology is a great candidate to be used in harsh environments.
