Aratas launches high-voltage SiC MOSFET relay

As demand grows for more efficient, high-voltage power semiconductor technologies to support decarbonization and energy conservation, manufacturers are increasingly turning to silicon carbide (SiC)-based solutions. These technologies can improve performance across applications ranging from renewable energy systems and data centers to industrial automation and transportation. Against this backdrop, Aratas America LLC (Aratas), formerly OMRON Electronic Components, announced the launch of its G3VH high-load-voltage SiC MOSFET relay.

The G3VH is a next-generation relay designed to support high-voltage switching applications requiring load voltages of 1,800 V or 3,300 V. By leveraging SiC MOSFET technology, the relay delivers enhanced voltage withstand capability, low ON resistance, low leakage current, and reliable high-speed switching while minimizing power loss and heat generation. The G3VH enables equipment manufacturers to develop smaller, more efficient high-voltage systems without compromising performance or reliability.

Unlike conventional silicon-based power semiconductors, SiC technology enables significantly higher dielectric breakdown strength, allowing the G3VH relay to support higher-voltage applications while maintaining a compact footprint. Available in both PCB-terminal and surface-mount DIP 6-pin packages, the G3VH combines high electrical performance with space-saving design for next-generation equipment.

Key features and benefits of the G3VH include:

• Improved defect detection and conformance testing accuracy
• Reduced inspection times
• Support for high voltage and high withstand voltage
• Low on-resistance, high dielectric strength, and high-speed switching

The G3VH series is available in 1,800 V and 3,300 V models and provides 5,000 Vrms dielectric strength between the input and output. Low ON resistance, low leakage current, and high-speed switching help improve system efficiency while supporting operation in demanding high-voltage environments.

The G3VH relay is well suited for semiconductor test equipment, battery management systems, measuring instruments, and other applications requiring precise, reliable high-voltage switching. Its compact footprint also supports equipment miniaturization while contributing to improved measurement accuracy, greater stability, and faster inspection throughput.
