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.
EL SEGUNDO, Calif.— April 2020 — 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.
In this article, we show that high electron densities and very low temperature coefficients give the eGaN FET major advantages over the power MOSFET needed for today’s high performance applications. High electron density yields superior RDS(ON), while positive temperature coefficients inhibit hot spot generation within the die, resulting in superior Safe Operating Area capabilities.

eGaN FETs exhibit a positive temperature coefficient across their entire operating range, thus overcoming a performance limitation of the silicon MOSFET.
EL SEGUNDO, Calif.—September 2012 — Efficient Power Conversion Corporation (EPC) is releasing safe operating area (SOA) data for their entire product line of eGaN FETs. The positive temperature coefficient across virtually their entire operating range allows a square SOA limited only by average device temperature.
