GaN eases Silicon out

Just like life’s reality, when the aged leaves the center stage for the younger ones, Silicon is taking the bow. The advent and adoption of Gallium Nitride (GaN) have succeeded in gradually easing out the old reliable Silicon. For over four decades, power management efficiency and cost have improved steadily as innovations in power MOSFET structures, technology, and circuit topologies have kept pace with the growing need for electrical power. In the new millennium, however, the rate of improvement has slowed dramatically as the silicon power MOSFET approaches its theoretical bounds. At the same time, the new material, GaN is steadily progressing on its journey toward a theoretical performance boundary that is 6,000 times better than the aging silicon MOSFET and 300 times better than the best GaN products on the market today.
