GaN Reliability

This Phase 11 reliability report adds to the growing knowledge base published in the first ten reports [1-10] and covers several key new topics. Gallium nitride (GaN) power devices have been in volume production since March 2010 and have established a remarkable field reliability record. This report will discuss the strategy used to achieve this track record that relied upon tests forcing devise to fail under a variety of conditions to create strong and strong products for the industry.
