EPC Demonstrates Field Experience of 123 Billion Device Hours, Unmatched by Silicon Power Devices

EPC’s Phase Eleven Reliability Report adds to the knowledge base published in the first ten reports. With this report, EPC demonstrates field experience of 123 billion device hours and a robustness capability unmatched by silicon power devices.

EPC announces its Phase Eleven Reliability Report, documenting the strategy used to achieve a remarkable field reliability record. This strategy relied upon tests forcing devices to fail under a variety of conditions to create stronger products to serve demanding applications such as lidar for autonomous vehicles, LTE base stations, vehicle headlamps, and satellites to name just a few.

Testing devices to the point of failure creates an understanding of the amount of margin between data sheet limits and products in application. More importantly, intrinsic failure mechanisms of devices are identified.  The knowledge of these intrinsic failure mechanisms is used to determine the root cause of failures. Knowledge of the behavior of a device over time, temperature, electrical or mechanical stress can provide users with an accurate representation of the safe operating life of a product over a more general set of operating conditions.

“eGaN devices have been in volume production for over ten years and have demonstrated very high reliability in both laboratory testing and high-volume customer applications,” said Dr. Alex Lidow, CEO and co-founder of EPC. “The release of EPC’s 11th reliability report represents the cumulative experience of millions of devices over a ten-year period and five generations of technology. These reliability tests have been undertaken to continue our understanding the behavior of GaN devices over a wide range of stress conditions.”
