In this article, the most common reasons for some customers to be slower in their embracing what is clearly a displacement technology for their older silicon-based power MOSFETs will be discussed. Without going into the detailed statistics, a list of reasons, in order of frequency is derived. This list is based upon the understanding that some applications will place higher emphasis than others on certain characteristics of GaN. Our discussion is limited to devices rated at less than 400 V, as that is the application focus for Efficient Power Conversion (EPC) FET and IC products.
