Aratas America LLC is targeting the high-voltage semiconductor market with the introduction of its G3VH series, a new line of silicon carbide (SiC) MOSFET relays designed to handle increased electrical loads. By transitioning from conventional silicon-based semiconductors to SiC technology, the company aims to provide equipment manufacturers with components capable of supporting load voltages of either 1,800 V or 3,300 V. This development arrives as industries such as renewable energy and data center management seek more efficient, compact switching solutions to support broader decarbonization and energy conservation efforts.
G3VH High-Voltage Switching Capabilities
The G3VH relay utilizes silicon carbide technology to achieve higher dielectric breakdown strength compared to traditional silicon-based power semiconductors. Aratas is positioning this product to enable the development of smaller, more efficient high-voltage systems by minimizing power loss and heat generation. The series is available in two specific voltage models: 1,800 V and 3,300 V. To ensure electrical robustness, the relays provide 5,000 Vrms dielectric strength between the input and output. The company is offering these components in both surface-mount DIP 6-pin packages and PCB-terminal packages, a move intended to support equipment miniaturization. By leveraging low ON resistance and low leakage current, the G3VH is designed to facilitate high-speed switching in demanding environments. This technical profile suggests the relay could assist manufacturers in improving measurement accuracy and stability while maintaining a compact footprint for next-generation electronic hardware.
Strategic Applications in Energy and Testing
Aratas is targeting several high-growth sectors with the G3VH rollout, specifically focusing on infrastructure that requires precise, reliable high-voltage switching. The company identifies semiconductor test equipment, battery management systems, and measuring instruments as primary use cases. In these applications, the relay's performance characteristics are intended to support faster inspection throughput and improved defect detection accuracy. For the energy sector, the move toward SiC technology aligns with the growing demand for efficient power semiconductor solutions in renewable energy systems. As a former spin-off of OMRON Corporation’s Device & Module Solutions Company, Aratas is utilizing this product launch to establish itself as an independent provider of advanced electronic technologies. The company's membership in the Solar Energy Industries Association further underscores its focus on the energy transition market, where high-voltage efficiency is increasingly critical for grid-connected and storage-based technologies.
Key Takeaways

EnergyInsyte's Take
In our view, Aratas America’s pivot toward silicon carbide (SiC) technology via the G3VH relay is a calculated response to the hardware constraints currently facing the energy transition. As battery management systems and renewable energy inverters demand higher voltages and tighter thermal management, traditional silicon components are reaching their physical limits. By offering a compact SiC solution with 5,000 Vrms dielectric strength, Aratas is attempting to capture the mid-to-high voltage switching niche. This signals that the industry is moving beyond mere capacity increases toward a focus on "power density"—achieving higher voltage handling within smaller, more efficient footprints.
