It is a fact that GaN transistors have increased the performance of power systems while reducing the relative cost of components. But what about quality and reliability?

In an interview with EE Times, Jim Witham, CEO of GaN Systems, highlighted how the power transistor industry is familiar with the qualification guidelines in the Joint Electron Device Engineering Council (JEDEC) standards for silicon transistors as the foundation. But with GaN, device material is different, and hence, the failure modes and mechanisms are different…
