Wolfspeed, Inc., a global leader in silicon carbide technology, has announced the appointment of Matthias Buchner as Senior Vice President of Global Sales and Chief Marketing Officer, effective December 1, 2025. Buchner will report directly to President and Chief Executive Officer Robert Feurle.
In his new role, Buchner will oversee Wolfspeed’s global sales and marketing operations, focusing on driving adoption of the company’s next-generation silicon carbide devices produced on its vertically integrated 200 mm manufacturing platform. His appointment comes at a pivotal time as Wolfspeed continues to expand its production capacity and strengthen its position in high-growth sectors such as automotive, renewable energy, industrial power systems, and AI-driven data infrastructure.
Buchner joins Wolfspeed from Infineon Technologies AG, where he served as Senior Vice President of Marketing for the Power & Sensor Systems Division. At Infineon, he managed strategic communication, partnerships, distribution, and marketing operations for a multibillion-dollar business. Over his two-decade career, he has held leadership roles at Infineon, Micron Technology, and other global technology companies, bringing extensive experience in silicon and silicon carbide power solutions, business development, and customer engagement.
Wolfspeed CEO Robert Feurle said the appointment underscores the company’s focus on strengthening customer relationships and expanding into new market segments. “Attracting a world-class sales and marketing executive like Matthias at this critical juncture underscores Wolfspeed’s commitment to capturing the immense opportunities ahead,” Feurle said. “His leadership experience across silicon and silicon carbide technologies will be instrumental as we advance in areas like AI data centers, renewable energy, and grid infrastructure. With Matthias joining our team, Wolfspeed is exceptionally well positioned to translate our vertically integrated silicon carbide platform into sustainable, profitable growth.”
Buchner said he is excited to join Wolfspeed at a time of major transformation for both the company and the industry. “Wolfspeed’s expertise in silicon carbide device production sets the standard for performance and quality,” he said. “My focus will be on building strong partnerships with our customers and accelerating the global transition from silicon-based to silicon-carbide-based technologies.”
His appointment comes as Wolfspeed continues to strengthen its operational and strategic foundation. The company recently completed a refinancing initiative to improve its financial position and streamline its operations. As part of these efforts, Wolfspeed plans to close its 150 mm device fabrication facility in Durham, North Carolina, by the end of 2025 and has decided not to proceed with a proposed fabrication facility in Saarland, Germany. These moves will consolidate Wolfspeed’s manufacturing footprint around its next-generation 200 mm silicon carbide platform, improving efficiency and long-term profitability.
Wolfspeed is also investing heavily in its U.S. manufacturing network, including an advanced materials factory in North Carolina, a device fabrication facility in New York, and a packaging plant in Arkansas. Together, these sites form a robust, fully integrated supply chain designed to support the company’s global customer base and future growth in the expanding silicon carbide market.
