Panasonic E-mode X-GaN adopted the HD (Hybrid Drain using p-GaN) -GIT structure could be used with higher reliability and robustness. We offer X-GaN in the most optimal package for a wide range of applications with DFN 6x4 of small footprint, DFN 8x8 of high frequency operational package. X-GaN has been qualified by conventional standards of JEDEC. In addition, X-GaN has been also qualified unique Beyond-JEDEC standard setting by Panasonic to dominate the new issues concerned from the GaN structure. Furthermore, X-GaN is designed to improve robustness against the issues that are simulated from how power devices are used in applications.
