Wolfspeed Inc.

Wolfspeed Inc. (WOLF) designs and manufactures silicon carbide (SiC) semiconductors as one of the few vertically integrated providers in the wide-bandgap semiconductor space. The company produces SiC substrates, epitaxial wafers, power devices and radio frequency (RF) components from crystal growth through finished product. This vertical integration gives Wolfspeed direct control over material quality and manufacturing processes across the entire supply chain.

Wolfspeed's power devices serve the electric vehicle, renewable energy, industrial and telecommunications markets. SiC-based components handle higher voltages and temperatures than traditional silicon, enabling smaller and more efficient power conversion systems. Automakers and EV charging infrastructure providers use Wolfspeed's MOSFETs and modules to extend driving range and reduce charging times. In renewable energy, the company's power devices improve inverter efficiency for solar and wind installations. The RF product line supports wireless infrastructure, aerospace and defense communications systems.

Wolfspeed also supplies bare SiC wafers and epitaxial materials to other semiconductor manufacturers. With dedicated SiC fabrication facilities, the company focuses exclusively on wide-bandgap technology rather than competing across the broader silicon semiconductor landscape.
