Better thermal management of eGaN FETs

A few simple thermal management guidelines can help conduct heat away from GaN FETs. Enhancement-mode gallium nitride (eGaN) FETs offer high power-density with ultra-fast switching and low on-resistance, all in a compact form factor. However, the power levels these high-performance devices provide can be limited by extreme heat-flux densities. If not managed properly, the generated heat can compromise reliability and performance. Fortunately, chip-scale packaging for eGaN FETs can be leveraged at the board-side and the backside (i.e., case) to better dissipate heat.
