Wolfspeed manufactures silicon carbide (SiC) semiconductors, producing both raw materials and finished power devices. As a vertically integrated manufacturer, Wolfspeed grows its own SiC crystals, processes them into wafers, and fabricates semiconductors like MOSFETs and Schottky diodes. SiC technology handles higher voltages and temperatures more efficiently than traditional silicon, making it suitable for high-power applications. The company operates two main product lines: Power Devices and Materials. Power Devices serve the automotive, industrial, energy, and aerospace markets, while Materials sells substrates and epitaxial wafers to other manufacturers. Wolfspeed requires high facility utilization to manage its fixed-cost structure. The company recently transitioned its production from 150mm to 200mm wafers at its Mohawk Valley facility to increase output and lower unit costs. Wolfspeed emerged from Chapter 11 bankruptcy in September 2025 and focuses on growth through electric vehicle (EV) adoption and AI data center power infrastructure. The company’s strategy targets 800-volt architectures for EVs and data centers, where SiC technology outperforms traditional silicon. Wolfspeed is also developing 300mm wafers for future use in thermal management and augmented reality systems.
