MOSFET relays deliver high sensitivity and dielectric strength ...

Omron Electronic Components Europe has further expanded its G3VM series line-up of MOSFET relays, which now offer increased sensitivity and higher dielectric strength capability. The new G3VM-61VY4 extends the 60-V SOP4 relay up to 0.7-A continuous load current with 3750 Vrms dielectric strength, whilst the 350-V G3VM-35VY1 increases continuous load to 110 mA with 3750 Vrms dielectric strength between I/O. The latest Omron relays conform to SOP4 special format — 2.10-mm in height, 3.7-mm wide and with 7.0-mm length. They share the same mounting pad footprint as that used for existing SOP4 relays. G3VM-61VY4 and G3VM-351VY1 relays are available now with the flexibility of small minimum order quantities from 500 pieces per taping type, and 125 pieces per stick. The high dielectric strength of the new models supports any applications requiring high isolation between inputs and outputs. The high-sensitivity G3VM-61VY4 and G3VM-351VY1 are especially suitable for sensor applications, for example transferring sensor signals and output signal switching from control units in security systems.

The MOSFET relays lead the industry in optical semiconductor technology, using an input LED, with a Photodiode Dome Array (PDA) used as a photocoupler and MOSFET chip in the load switching current. In addition to being maintenance-free, the MOSFET relay features high-speed operation and compact size, further enabling the replacement of mechanical relays.

Both new models will provide further lowering of power consumption during switch-on, as well as reducing input current by one third during operation. The MOSFET relays contribute to smaller and denser equipment than equivalent mechanical devices. Compared to reed relays, power consumption on the input is exceptionally low, further contributing to energy-saving equipment.
