Abstract

Significant development resources have been expended and

Gallium Nitride (GaN) based power conversion devices are

now being introduced to the market on the heels of much

hype. It remains to be seen how widely GaN power

transistors will be adopted. Will GaN devices eventually

replace all Silicon power transistors? Or will there be peaceful

coexistence with complementary performance? Where will

GaN succeed and where will Silicon still thrive? This

presentation will attempt to answer these questions by

considering historical precedence, by considering relative

strengths and weaknesses of each technology, by examining

initial applications for GaN devices, and by peering into the

crystal ball and projecting GaN vs Silicon adoption trends.
