QUICK START GUIDE EPC9079
THERMAL CONSIDERATIONS
The EPC9079 development board showcases the EPC2046 eGaN FET. The
EPC9079 is intended for bench evaluation with typical room ambient
temperature. The addition of heat-sinking and forced air cooling can
significantly increase the current capability of these devices, but care
must be taken to not exceed the absolute maximum die temperature
of 150° C.
NOTE. The EPC9079 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.
