Omron MOSFET Relay Minimises Leakage for Maximum Test Accuracy, samples available from Anglia.

Date Published : 06/05/2020 Share with:

In a world first for semiconductor and other test equipment, Omron Electronic Components Europe has created a MOSFET relay module that minimized leakage current. The G3VM-21MT relay from Omron combines the advantages of mechanical and MOSFET relay technologies to provide the ultimate test switching solution

The G3VM-21MT MOSFET relay has a unique T- circuit structure, this allows the device to offer an exceptionally low leakage current of just 1pA (pico-Amp) or less, providing accurate measurements in all types of test equipment. Mechanical reed relays have previously been the preferred option for semiconductor and other test equipment, in part due to their low leakage current. However, mechanical reed relays have a much lower lifespan due to abrasion of contacts which reduces measurement accuracy over time. In intensive use, frequent replacement of traditional mechanical reed relays is necessary pushing up the maintenance costs and increasing down time of the test equipment.

The G3VM-21MT MOSFET relays unique ‘T-Type Circuit structure’ sends most leakage current to ground.

This means the G3VM-21MT effectively combines the advantages of the mechanical and MOSFET relays to provide an accurate, compact and long-lasting switching solution with no mechanical contacts.

Click below for an overview of the G3VM-21MT MOSFET Relay

The G3VM-21MT MOSFET relay is offered in SPST contact form with no configuration required and features an impressive maximum load voltage of 20V and isolation performance less than -30dB at 1 GHz. The relay is capable of delivering a continuous output current of up to 200mA and has an operating temperature range of -20°C to +85°C.

The relay is housed in a compact surface mount module measuring just 5mm x 3.75 mm x 2.7mm.
