What SemiQ does
SemiQ Inc. is a privately-held US silicon carbide (SiC) power semiconductor company headquartered in Lake Forest, California. Founded in 2007, the company manufactures and supplies a portfolio of wide-bandgap power components including SiC power modules, MOSFETs, Schottky diodes, and SiC epitaxial wafers used in high-efficiency power conversion systems.
The company's flagship offering is the QSiC Dual3 series of 1200-V SiC half-bridge MOSFET modules, which achieve a power density of 240 W/in³ with an RDS(on) of 1 mΩ in a 62×152-mm package. The modules are screened to exceed 1350 V, rated for junction temperatures from -40°C to +175°C, and designed to replace silicon IGBT modules with minimal redesign. Target applications include liquid-cooled AI data center power conversion, grid-tied energy storage converters, industrial motor drives, uninterruptible power supplies (UPS), and electric vehicle systems.
SemiQ operates a channel-based go-to-market model, with NAC Semi serving as its distribution partner across North America, providing engineering support to automotive, industrial manufacturing, and data center customers. Pricing is not publicly disclosed. The company is led by President and General Manager Michael T. Robinson and competes in the global SiC power semiconductor market alongside STMicroelectronics, Infineon, and Microchip; that market was valued at USD 3.1 billion in 2025 and is projected to grow at a 14.9% CAGR to USD 8.9 billion by 2033.
