GaN more Robust and Reliable than Silicon

GaN Device Reliability

eGaN® devices have been in volume production since March 2010 and have demonstrated very high reliability in both laboratory testing and high-volume customer applications. eGaN devices have a remarkable field reliability record.

EPC has undertaken extensive reliability testing to continue the understanding of the behavior of Gallium Nitride devices over a wide range of stress conditions.

The results of these reliability studies show that GaN is an extremely robust technology that continues to improve at a rapid pace.

EPC is committed to subjecting GaN devices to rigid reliability standards and sharing the results with the power conversion industry. We continue to add new documents to this knowledge base regularly.
