Evolving eGaN FETs for power electronics

Evolving eGaN FETs for power electronics

The combination of lower on-resistance, faster switching speeds, lower thermal impedance, and smaller physical size of eGaN FETs continues to raise the bar for power transistor performance. As GaN technology matures, not only does the performance of these transistors rapidly improve, but significant reductions in cost are also realized. Not only will GaN devices continue to enable new applications, they will replace silicon power transistors in cost-sensitive applications as well. As a matter of fact, the first signs of this happening are already here.
