Investment and M&A to reshape Power SiC and GaN markets

Multiple SiC players announced plans for capacity expansion in order to fulfill the requirement of end-systems, especially in automotive, in the coming years. Leading devices players, such as STMicroelectronics, Infineon, Wolfspeed, onsmei and ROHM are all working on facilities built-up in various locations. At SiC wafer level, even more projects are on-going, with massive injection of resources of new entrants, we are witnessing SiC growing with a strong momentum. In addition, 8” SiC platform accounts for the technology to scale up and to gain significant cost reduction. Wolfspeed’s MHV fab is the only 8” SiC wafer fab operating as of 2023, and the company announced to build another 8” fab in Germany, with the investment of automotive tier-1, ZF. Other device players are also accelerating the 8” production, expected to have initial volume by the end of 2023. On the other hand, Tesla as the major SiC user announced to have 75% less SiC in its future powertrain, in this Monitor, we provide the scenario analysis based on current trends of technology and market, along wit the first edition of 2028 SiC market forecast.

Regarding the Power GaN market, Infineon Technologies’ acquisition of GaN Systems is highly significant for the power electronics industry: it is by far the largest sale to date within the power GaN sector, and the $830 million purchase price – around 18% of Infineon Technologies’ total annual power electronics’ revenue – comes 4 times higher than the value of the entire power GaN market as of 2022. The leading company in power electronics investing so heavily in a relatively young company with relatively small annual revenues is a momentous move, signifying Infineon Technologies’ desire to capitalize on GaN’s growth potential and cement its leadership in power electronics.

SiC and GaN have become key segments in the power semiconductor industry

SiC and GaN are continuing the rapid market evolution started in 2018-2019, but now have different drivers behind their growth. At first, disruptive car maker Tesla adopted SiC in its inverters. But now, another trend is reshaping the electric vehicle (EV) market, namely fast 800V EV charging, allowing shorter charging stops. SiC is the enabler, with promising performance and a growing supply chain. As of 2023, high-volume EVs, including BYD’s Han and Hyundai’s Ioniq5, using SiC are being shipped. Leading device players, such as STMicroelectronics, Infineon, Wolfspeed, onsemi, and ROHM, generated record revenues in 2022. They will each move forward to $1B SiC revenue in the 2023-2025 timeframe, with the total market exceeding $8B in 2028. Beyond automotive, now industrial, energy, and rail applications provide extra growth momentum. Capacity build-up, business integration, and new business models will lift SiC to another level in years to come.

Meanwhile, GaN is still progressing in consumer applications, mainly fast chargers for smartphones. Power Integrations and Navitas lead the market with multiple design wins with phone makers. Innoscience also announced shipments of over 100M devices by 2022, mainly targeting consumer power supplies. In Q1-23, Navitas has achieved a design win for Realme’s GT 3 240W ultra-fast ‘in-box’ charger. We observe a clear trend to target power higher than 100W for smartphone fast chargers, which would increase the GaN content. In the long term, telecom and datacom applications, which will need high-efficiency power conversion to meet CO2 emission objectives, and on-board chargers as well as DC-DC converters in EVs are opportunities for GaN to grow and exceed a $2B business in 2028.
