STMicroelectronics Ampere SiC Power Modules for EV 2026
STMicroelectronics and Ampere are targeting 2026 commercialization of SiC power modules for next-generation EV traction inverters.
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.
STMicroelectronics SiC New Fab: Mass Production Progress
STMicroelectronics aims to capture EV and industrial demand by incrementally expanding its SiC power semiconductor fab in Catania, Italy, a move that, considering the scale and timing of investment and the pressure to monetize its SiC business, signals more than just a capacity increase.
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.
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.
SiC investment: EU approves EUR 659M, China raises capital
On July 14, 2026, the European Commission approved EUR 659 million in state aid for four semiconductor facilities in Germany. Element 3-5 receives EUR 353 million for SiC epitaxial wafers and Vishay EUR 214 million for a power-MOSFET plant. In China, AccoPower (芯聚能) and Xinyueneng (芯粤能) reportedly raised more than RMB 700 million in a Series D round. Public and private capital is accelerating into SiC supply chains in Europe and China.
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.
