SemiQ is a specialist in silicon carbide power technology, dedicated to helping engineers push the boundaries of efficiency, thermal performance and long-term reliability in demanding applications. The company develops and manufactures SiC diodes, MOSFETs and power modules designed for real-world operating conditions, where robustness, switching performance and predictable behaviour matter as much as raw efficiency gains. SemiQ’s engineering culture is built around deep device-physics expertise and a commitment to controlled manufacturing processes that ensure consistent electrical characteristics across every production run.

The company’s portfolio is used across industrial power supplies, EV charging, energy storage, motor drives and a range of high-power conversion systems where SiC materials offer measurable performance improvements over legacy silicon. SemiQ focuses on giving design teams devices that are not only fast and efficient, but also engineered to handle electrical stress, thermal cycling and long-term field operation. This includes careful optimisation of die structures, package design and test methodologies that reflect how power electronics behave in real systems rather than idealised lab conditions.

SemiQ’s technical team provides application support to help engineers integrate SiC devices effectively, address layout and gate-drive considerations, and achieve stable switching performance with minimal tuning. By working closely with customers, the company ensures its devices deliver predictable behaviour across a wide range of topologies, including hard-switching, soft-switching and high-frequency designs.

With a manufacturing base in Pennsylvania and a focus on quality control at every step of the process, SemiQ positions itself as a partner for companies moving to wide-bandgap technology and seeking devices that combine performance with reliability. The company continues to expand its portfolio to support higher power levels, improved thermal characteristics and more efficient power-conversion architectures as silicon carbide adoption accelerates across the industry.
