2020 ushered in a wave of GaN transistors in applications from automobiles to audio amplifiers. We talked with GaN Systems CEO Jim Witham to find out why he thinks 2021 could see even more GaN adoption.

While gallium nitride (GaN) transistors were once the musings of university research projects 20 years ago, these devices are now widely adopted across the industry—especially in 2020.

GaN transistors are now a popular substitute for silicon-based FETs because they offer extremely high electron mobility. This also gives GaN a leg up with smaller on-resistances and significantly faster switching speeds than silicon-based transistors. ..
