SiC and GaN will compete with silicon from low to high power

The SiC market is expected to treble and GaN is expected to explode – if challenges are overcome

In 2014, the SiC chip business was worth more than $133M. As in previous years, power factor correction (PFC) and photovoltaics (PV) are still the leading applications.

SiC diodes represent more than 80% of the market. In 2020, diodes will remain the main contributor across various applications, including electric and hybrid electric vehicles (EV/HEV), PV, PFC, wind, Uninterruptible Power Supplies (UPS) and motor drives.

SiC transistors will grow in parallel with diodes, driven by PV inverters. Challenges must be overcome prior to the adoption of pure SiC solutions for EV power train inverters, which is nevertheless expected by 2020.

Including the growth in both diodes and transistors we expect the total SiC market to more than treble by 2020, reaching $436M.

GaN potentially has a huge Total Accessible Market (TAM), and its adoption would therefore be significant. The starting point and the growth rate are directly linked to two important questions:

  • How will the emerging applications of low voltage GaN expand and how GaN will be adopted by these applications?
  • Will 600V devices make their way into market?

Yole Développement has integrated these variables in developing two scenarios for the GaN device market up to 2020. The analysis is based on the penetration rate of GaN in different applications including DC-DC conversion, Lidar, envelope tracking, wireless power, and PFC… We estimate the GaN device market size will be $303M in 2020 in the nominal scenario. In the accelerated scenario, where low voltage GaN and 600V GaN are rapidly adopted, the figure for 2020 is $560M. Emerging applications, namely envelope tracking, wireless power and Lidar, together will consume one third of GaN transistors. In both scenarios low voltage applications below 200V are expected to be the major contributors to the market. We invite you to read the report to find out more.
