MOS FET Relays

In order to address environmental issues, energy-saving design in various devices needs to be improved to reduce power consumption. One of the environmental measures is to reduce the power consumption of the component itself by selecting high-sensitivity type relays for the customer's equipment. High-sensitivity MOS FET relays can be driven with less current than our conventional relays, contributing to lower power consumption.

(calculated based on recommended operating conditions for each type)

Conventional relay: G3VM-61VY3 100% High-sensitivity type: G3VM-61G2 73% reduction in current consumption*1 *1 G3VM-61G3 93% reduction in current consumption*1 *1

[The value DMS provides]

  • Reduction of the drive current of MOS FET relays enables more energy-saving options for equipment.
  • * When replacing from the same packaged product, there is no need to change the pattern design of the mounting section. * The input current must be redesigned (e.g., reviewing the limiting resistor value) depending on the operating conditions of the MOS FET relay you have selected.

Mechanism for driving MOS FET relays with lower current consumption

Unlike mechanical relays, MOS FET relays are structured so that the PDA element receives the luminous energy emitted by the LED element to generate electricity, which operates the output-side MOS FET. The light-emitting and light-receiving elements are the key components of the current consumption. OMRON's high-sensitivity type MOS FET relays can be driven with lower current consumption. This has become possible because they are designed to be energized even when the light-emitting energy of the LED element is small by increasing the sensitivity of the PDA element, which is the light-receiving element.

Internal structure of MOS FET relay Difference between conventional and high-sensitivity types

Conventional relay: Sensitivity of PDA element: Normal, Light intensity: Operates at high intensity　High-sensitivity type MOS FET relay: Sensitivity of PDA element: High, Light intensity: Operates at low intensity
