Renesas: 10-Year SiC Wafer Supply Deal with Wolfspeed
Renesas and Wolfspeed's 10-year SiC wafer agreement shows how supply, wafer quality, and 8-inch migration are becoming strategic assets.
Wolfspeed: Changing SiC Procurement Risks Post-Restructure
Wolfspeed emerged from Chapter 11 in September 2025. While the risk of financial insolvency has been resolved, the Mohawk Valley Fab continues to run at utilization rates in the low 20s, shifting the fundamental risk from 'bankruptcy concern' to 'utilization-rate dependency.' Drawing on the strategic equity relationship with Renesas and Q3 FY2026 results, this article reexamines the evaluation criteria for SiC procurement.
Wolfspeed: Gen 5 SiC Cuts Specific On-Resistance up to 27%
On June 9, 2026, Wolfspeed announced its fifth-generation SiC technology, reducing specific on-resistance (RSP) by up to 27% versus competing 1200V solutions. Covering 1200V/750V on a production-ready 200mm platform, it targets automotive traction inverters, industrial power supplies, and EV charging infrastructure.
SiC Suppliers: Alternative Sources to Reduce Wolfspeed Use
Wolfspeed's bankruptcy and restructuring has highlighted the risks of single-supplier dependency in SiC procurement. This guide compares Infineon CoolSiC, onsemi EliteSiC, ROHM, Mitsubishi Electric, Fuji Electric, and Chinese manufacturers on key characteristics and selection criteria, providing a framework for building a multi-supplier strategy.
Renesas Acquires Transphorm GaN Business
Renesas Electronics has agreed to acquire Transphorm, a pioneer in GaN-on-SiC vertical GaN structures, in a deal set to fundamentally transform its power semiconductor portfolio in 2025.
RIR Power's India-First SiC Vertical Push
RIR Power Electronics, founded in 1969, rebranded in September 2025 as India's first vertically integrated SiC semiconductor maker. It is building a SiC power campus in Odisha with INR 6.18 billion in investment, listed on the NSE in July 2026, and targets FY2027 mass production.
Navitas and Magnachip: 3300V SiC licensing
On July 23, 2026, Navitas announced it will license GeneSiC Gen4/Gen5 technology, covering 1200V, 2300V, and above 3300V, to Magnachip. Magnachip will transfer and localize the technology at its Korean fab. The target is high-voltage grid infrastructure, industrial electrification, and energy storage rather than EVs, showing SiC competition broadening from automotive into power and industrial markets.
STMicroelectronics Q2 2026: double-digit SiC growth and DC upside
STMicroelectronics reported Q2 2026 revenue of USD 3.49 billion, up 26% year on year, with a 34.8% gross margin. It expects double-digit SiC revenue growth in 2026, supported by the move from 6-inch to 8-inch wafers, and raised its AI data-center targets to over USD 1 billion in 2026 and over USD 2 billion in 2027. Q3 guidance is USD 3.70 billion and Q4 is expected to exceed USD 4 billion.
GaN patent war: Infineon ITC win and Wolfspeed suit
Infineon secured a final U.S. ITC import and sales ban against Innoscience GaN products, the first large case in which European IP excludes Asian products from the U.S. market. Wolfspeed also sued Navitas for patent infringement, turning GaN patent battles into procurement risk.
SiC solid-state transformers: AIDC deployment begins
SiC solid-state transformers (SSTs) have entered the commercial stage. Weiguang Energy has shipped more than 100 SSTs and secured over 40GW of capacity across two sites. Delta has announced an SST delivering MW-class power in 1m² with more than 50% space savings, while Eaton offers its 2.5MW MV SST 2.0. This article reviews the move to direct conversion from medium voltage to 800VDC using primary information.
