GaN Transistors Make Inroads Commercially While Technology Expands To Higher Voltages

Focus:

For the last few years, we have heard a lot about the benefits of gallium nitride (GaN) technology and the virtues of GaN-based power FETs and HEMTs. The reliability of these transistors has also been improving significantly, while the cost factor has been declining as developers migrate to larger silicon substrates. In this column, Bindra examines recent GaN product developments from established and new suppliers. He also identifies the companies that are expected to soon join the supplier base as the technology moves up in voltage to address a wider range of applications. Bindra also looks at how the new GaN power devices are faring in the marketplace by discussing some of the applications where product manufacturers have begun to adopt these components as silicon replacements.
