Fitting in!

Equipment designers dealing with tight space constraints or low-strength signals in sensing applications can now overcome these challenges using new G3VM MOSFET relays announced by Omron Electronic Components Europe. The two families being added to the Omron G3VM line-up are a range of tiny VSON devices measuring 2.45mm x 1.45mm x 1.30mm, and ultra-sensitive relays that can be triggered by a signal of just 0.2mA.

Six new relays are offered in the VSON package, which has little more than half the footprint of competing USOP devices. The package features large, efficient bottom-side contacts, with edge metallisation allowing easier solder-joint inspection. Rated load voltages range from 20V in G3VM-21UR1/10/11 to 100V in the G3VM-101UR.  40V, 50V, 60V, 75V and 80V ratings are also available, and rated continuous load current is from 100mA to 1A. On-resistance down to 0.18°Ω  helps minimise power losses, and fast switching times allow use with high-frequency signals in various test & measurement, telecom and wireless applications, as well as portable consumer devices such as cameras. Omron is to launch a further six VSON devices Spring 2015.

With extremely low actuation current of 0.2mA, Omron’s new ultra-sensitive G3VM relays (G3VM-xxG1/G2/G3) require only around 20% of the signal strength of earlier-generation high-sensitivity devices. This makes them ideal for use in sensing applications such as the motion detectors of security systems, as well as various industrial applications, test & measurement equipment, and energy-conscious or battery-powered devices that require extended operating lifetimes. The relays are packaged as space-efficient SOP-4 devices, and offer a wide range of load voltages from 60V to 600V with rated continuous load current from 70mA to 400mA.
