There has been an enormous amount of reliability testing performed on GaN devices from several manufacturers, including EPC, GaN Systems, Panasonic, and Transphorm. It has been shown that GaN devices can not only pass standard JEDEC testing originally designed for silicon-based power MOSFETs, but devices from both Transphorm and Efficient Power Conversion have passed the more-stringent automotive qualification requirements (AEC Q101). Moreover, EPC’s eGaN transistors and integrated circuits with chip-scale packaging do not have any of the reliability failure mechanisms brought on with traditional MOSFET packaging. As evidence of basic reliability in actual real-world applications, EPC has tracked over 30 billion hours in customer applications over the past four years…with only three device failures. This is a record unmatched by even the silicon power MOSFET!
