What is the temperature range for extended application?
EPC’s product family have maximum operating temperature ratings at 150°C. GaN transistors in general are capable of operating at temperatures as high as 300°C. EPC’s devices are mounted as flipchips in a chip-scale package format onto PCB’s using lead free solder. This, plus the maximum temperature allowed at the surface of a commercial PCB is typically no higher than 105°C, are the two reasons EPC has not initially rated these parts at higher temperatures.
