Omron Corporation (Headquarters: Kyoto, Japan. CEO: Yoshihito Yamada) will introduce its new MOSFET*1 relay module “G3VM-21MT” worldwide on December 2, 2019. This product will be the first in the world*2 to use “T-shaped circuit structure”*3. This relay module has a T-shape structure and is composed of solid-state relays with compact size and long service life. It can output signals without physical contact, thereby minimizing leakage current, which has long plagued semiconductor test equipment*4. The G3VM-21MT provides highly accurate measurements and improves the performance of electronic components.
The G3VM-21MT is capable of switching measurement signals in test equipment used primarily for electrical testing of semiconductor devices. In addition to its compact size and longer service life, the G3VM-21MT is also the world’s first MOSFET relay module with “T-shaped circuit structure”, which consists of three MOSFET relays, which helps minimize leakage current without affecting the detection accuracy of test equipment. At the same time, high measurement accuracy can be achieved and the maintenance frequency of testing equipment can be reduced.
In the digital age, as electronic components become more diverse in functionality and production volumes increase, the demand for higher performance semiconductor test equipment is growing. Mechanical reed relay*5 is a component used for high-precision measurements in semiconductor test equipment. Its leakage current is extremely low, but due to wear it must be replaced regularly, perhaps several times a month, resulting in damage to the contact points. affect the accuracy of measurements. Such maintenance work can have a significant impact on performance, which is why solid state relays have long been in demand due to their longer lifespan. To date, MOSFET relays are considered unsuitable for precision electrical testing due to the technical difficulty of reducing leakage current associated with their characteristics, and are not used in test equipment requiring high reliability.
To meet these needs, we have successfully introduced relay module products to the market using Omron’s accumulated electronic component technology over many years. It uses a “T-shaped circuit structure” to significantly reduce the leakage current to less than or equal to 1 pA (). one part per trillion). The goal of reducing the leakage current in solid state relays as close to zero as possible eliminates leakage current problems and improves the reliability of test equipment. Additionally, by integrating long-life MOSFETs into relay modules, maintenance downtime can be reduced, a long-standing problem for mechanical relays. With the launch of the G3VM-21MT, Omron will strive to contribute to improving the performance of electronic components and support the development of digital transformation of society.

Increased device reliability by reducing leakage current to 1 pA or less. Leakage current is a long-standing problem with solid-state relays, and the G3VM-21MT helps solve this problem by reducing leakage current to 1 pA or less. The G3VM-21MT successfully achieves actual performance below or below 0.1 pA while minimizing the impact on application measurement accuracy.
Extended service life and significantly reduced maintenance frequency. The output circuit of the G3VM-21MT relay module consists of semiconductor MOSFETs without physical contacts, so there is no need for contact maintenance due to wear or scratches as there will be no damage due to disconnection. Arc occurrence and circuit closure.
Reduce installation space. Save space and wires for high-density installations. The G3VM-21MT has a compact size of 5mm × 3.75mm × 2.7mm by incorporating complex input and output circuitry into the internal module, ultimately simplifying PCB installation. .
