GE Aerospace and Wolfspeed Collaborate to Accelerate High-Voltage Silicon Carbide (SiC) Adoption

Key Terms

silicon carbide technical

Silicon carbide is a hard, durable material made from silicon and carbon, often used in industrial applications like cutting tools and electronics. Its ability to withstand high temperatures and conduct electricity efficiently makes it valuable in manufacturing advanced electronic devices. For investors, companies working with silicon carbide are seen as key players in the growing market for high-performance electronics and energy-efficient technologies.

mosfet technical

A MOSFET is a tiny electronic switch used to control the flow of electricity in chips and circuits, functioning like a faucet that turns current on or off and adjusts how much passes through. Investors watch MOSFETs because their performance, cost and availability affect product power efficiency, manufacturing yields and supply chains for industries from consumer electronics to electric vehicles, which in turn can influence companies’ margins and growth prospects.

metal-oxide-semiconductor-field-effect transistors technical

A metal-oxide-semiconductor-field-effect transistor (MOSFET) is an electronic switch that controls the flow of electricity in a circuit using a voltage signal, much like a faucet controls water flow. MOSFETs are the basic building blocks of modern chips and power systems, so improvements in their size, speed or efficiency can directly affect product performance, manufacturing costs and demand across industries—making them important indicators for investors in semiconductor and electronics companies.

solid-state transformers technical

A solid-state transformer is an electrical device that uses power electronics instead of heavy metal coils to change voltage and steer electricity, acting like a digitally controlled, much lighter version of a traditional transformer. For investors, it matters because these units can boost efficiency, add fast remote control and protection features, and enable modern grid uses — such as electric-vehicle charging and renewable energy integration — which can change infrastructure costs and create new technology markets.

siC technical

Sic is a short notation placed immediately after a quoted word or passage to show the text is reproduced exactly as it appeared in the original source, even if it contains a typo, odd phrasing, or factual error. For investors, it signals that any mistake or unusual wording came from the original speaker or document, not from the publisher—like an editor saying “this is how it was said,” which helps with accuracy, responsibility, and legal clarity.

Announcement highlights:

• GE Aerospace and Wolfspeed enter into a Memorandum of Understanding (MOU) to accelerate the commercial readiness and market acceptance of high-voltage silicon carbide solutions
• MOU includes the supply of Wolfspeed’s 10 kV MOSFET die and jointly determining standard high-voltage power module formats for commercial introduction.
• The scope of the MOU aligns with the United States Government’s stated priorities of accelerating critical technologies for achieving faster time-to-power for strategic markets such as Artificial Intelligence.

DURHAM, N.C.--(BUSINESS WIRE)-- GE Aerospace (NYSE: GE) and Wolfspeed Inc. (NYSE: WOLF) today announced that they have entered into a Memorandum of Understanding (MOU) to collaborate on accelerating the adoption of high-voltage silicon carbide across the industrial, aerospace and defense markets.

Under the MOU, the companies plan to develop standards for high-voltage silicon carbide-based power modules to support solid-state transformers, industrial electrification, and next-generation aerospace & defense (A&D) platforms while strengthening supply chain resilience. These higher-voltage power modules will enable systems with fewer series-connected devices and less complexity, enabling solutions that are more compact, efficient and reliable.

“Separately, our two companies have contributed to several industry-first technologies,” said Kris Shepherd, president of Electrical Power for GE Aerospace. “Together, we’re ready to shape a robust value chain of high-power silicon carbide based on a mutual appreciation for achieving smaller, reliable and more efficient high-voltage end systems.”

"As AI, electrification, and defense platforms push power demands higher and timelines shorter, GE Aerospace and Wolfspeed are uniquely positioned to deliver the high-voltage silicon carbide building blocks the market needs," said Robert Feurle, CEO at Wolfspeed. “By securing domestic sourcing of high-power silicon carbide modules, the two companies are jointly committed to enabling systems that improve efficiency and lower time-to-power. High-voltage silicon carbide is finally production-ready exactly as the market confronts a power-delivery crunch legacy silicon cannot solve.”

Leveraging silicon carbide, GE Aerospace recently qualified high-voltage power units for U.S. military ground vehicles, marking them production ready. The team also successfully demonstrated their fourth generation of silicon carbide power MOSFET (metal-oxide-semiconductor-field-effect transistors) devices at the company’s Research Center in Niskayuna, N.Y. that will improve switching speed, efficiency, and durability.

Wolfspeed leads the industry in high-volume 200 mm silicon carbide manufacturing and recently introduced the world's first commercially available 10 kV SiC MOSFET — honored as a PCIM Top Innovation — giving the industrial, AI, and aerospace & defense markets a production-ready path to high-voltage power.
