With the growing prevalence of SiC power semiconductors, voltages in power electronics, power supply systems, and electromobility are increasing. This creates new demands for switching technology.
In automated test systems especially, high DC voltages must be reliably switched without compromising size, service life, or test speed. OMRON offers the G3VH series for these applications. This SiC-based MOSFET relay can handle load voltages of 1,800 or 3,300V and is currently available at www.rutronik24.com.
High voltage withstand in a compact design
The G3VH series combines high load voltages with low turn-on resistance and fast switching performance. The insulation voltage between the input and output is 5,000 Vrms. This makes the relay particularly suitable for high-voltage DC applications and testing modern power semiconductors. Compared to conventional MOSFET relays, this series enables higher switching voltages. Compared to reed relays, the focus is on a more compact design and the high reliability of the semiconductor solution.
The combination of high insulation performance and fast switching is particularly attractive to developers of ATE and measurement systems. This feature supports precise fault and conformance detection and can shorten test times. Thanks to its wear-free semiconductor design, the relay is ideal for long-lasting, low-maintenance systems. The DIP6 package measures just 8.8 × 6.4mm and is available with PCB or SMD terminals.
