THERMAL CONSIDERATIONS
The EPC9080 development board showcases the EPC2045 and EPC2022
eGaN FET. The EPC9080 is intended for bench evaluation with low ambient
temperature and convection cooling. The addition of heat-sinking and
forced air cooling can significantly increase the current rating of these
devices, but care must be taken to not exceed the absolute maximum die
temperature of 150° C.
NOTE. The EPC9080 development board does not have any current or thermal
protection on board.
For more information regarding the thermal performance of EPC eGaN FETs, please

Efficient Power Conversion, First Edition, Power Conversion Publications, 2015.
