Infineon's chief marketing officer joins Wolfspeed
SiC specialist Wolfspeed has appointed Matthias Buchner as SVP of global sales and chief marketing officer, effective December 1, 2025. Buchner will report directly to CEO Robert Feurle.
Buchner joins Wolfspeed from Infineon Technologies AG, where he most recently served as SVP of marketing for the Power & Sensor Systems division, responsible for strategic communication, partnership management, distribution marketing, digital marketing and marketing operations for a $3+ billion business.
Over his more than 20-year career, he has held senior leadership positions at Infineon, Micron Technology, and other technology companies, with deep experience in both silicon and SiC power solutions, business development, and global customer engagement.
In this new role, Buchner will lead Wolfspeed’s sales and marketing organisations with a focus on leveraging the company’s next-generation SiC devices, produced on its 200 mm manufacturing platform. The appointment supports Wolfspeed’s strategy to broaden its customer base across diverse, high-growth markets including automotive, renewable energy, industrial power systems, and AI-driven data infrastructure.
“Attracting a world-class sales and marketing executive like Matthias at this critical juncture underscores Wolfspeed’s commitment to capturing the immense opportunities ahead,” said Robert Feurle, Wolfspeed’s president and CEO.
He added: “His global leadership experience across silicon and SiC technologies — spanning automotive, industrial, and other competitive markets — will be instrumental as we strengthen our customer relationships and expand into rapidly growing segments such as AI data centers, renewable energy, grid infrastructure, and aerospace and defence. With Matthias joining our team, Wolfspeed is exceptionally well positioned to translate our vertically integrated SiC platform into sustainable, profitable growth.”
Buchner said: “I am very excited to join Wolfspeed at this important moment for the company and the industry, Wolfspeed’s deep domain expertise in producing SiC devices sets the industry standard for performance and quality in today’s competitive landscape. Building strong, trusting relationships with our customers will be a key focus for me immediately out of the gate, as we work together to accelerate the global transition from silicon-based to silicon-carbide-based technologies.”
Wolfspeed recently came out of Chapter 11 with a strategic refinancing initiative to strengthen its balance sheet and position it for sustained, profitable growth. In conjunction with this effort, Wolfspeed has rationalised its production footprint. This includes the planned closure of its 150mm device fab on the Durham campus by the end of calendar 2025, as well as the decision to discontinue development of a proposed fab in Saarland, Germany.
Wolfspeed’s manufacturing operations are now being focused around its next-generation 200mm SiC platform. Wolfspeed has invested in facilities in the US including its advanced materials factory in North Carolina, device fabrication operations in New York, and device packaging facility in Arkansas.
