Omron’s MOSFET relay boosts test accuracy
Omron Electronic Components Europe has created a MOSFET relay module that minimises leakage current.
With a T-circuit structure, the Omron G3VM-21MT offers low leakage current of 1 pico-Amp (pA) or less, giving accurate measurements in all types of test equipment.
Mechanical relays have previously been preferred in semiconductors and other test equipment, in part owing to their low leakage current. However, mechanical relays have a much lower lifespan because of the abrasion of contacts, which over time reduces measurement accuracy. In intensive use, frequent replacement may be necessary pushing up maintenance costs.
The compact size of 5mm x 3.75 mm x 2.7mm is achieved by the incorporating the T-circuit into the module. The device is surface mounted and comes in SPST with no configuration required. It features a maximum load voltage of 20V and its isolation performance is less than -30dB at 1GHz.
Omron is planning further T-circuit MOSFET relay modules, including a high current and high voltage model.
Omron Electronic Components Europe is a leader in electromechanical PCB relays, as well as a leading supplier of components such as micro switches, MOSFET relays, DIP switches, photomicrosensors and connectors.
Omron offers a portfolio of innovative technologies including MEMs-based pressure, flow and thermal measurement sensors, human face and gesture recognition modules, vibration and tilt sensors.
The company supports its customers in Western and Eastern Europe, Russia and the CIS through eight regional offices, a network of local offices and partnerships with specialist, local, regional and global distributors.
Omron Electronic Components Europe is a subsidiary of the Omron Corporation, recognised worldwide for its electrical and electronic control equipment and component products.
