A metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a field-effect transistor (FET with an insulated gate) where the voltage determines the conductivity of the device. It is used for switching or amplifying signals It is a solid-state device that replaces a coil-activated mechanical switch with an optically isolated input stage driving a MOSFET.
It offers superior performance to an electromechanical relay in many applications. Internally, a MOSFET relay includes an input-side LED and an output side with a photodiode dome array (PDA), a control circuit, and an output FET block. The operation is as follows:
- The input driver circuit causes current to flow through the LED, turning it on. The driver circuit can be as simple as a pullup resistor on pin 1 and a switch to ground on pin 2.
- The light from the LED output travels through the silicone resin and is converted to voltage by the PDA.
- The PDA output drives the MOSFET output block via a control circuit. The output block contains a double MOSFET, allowing it to pass both AC and DC loads in either direction.

Compared to traditional relays, MOSFET relays offer many benefits, including lower maintenance costs, a smaller footprint, a longer lifetime (greater than 500 million operations), and higher-speed switching. MOSFET relays also outperform other electronic technologies such as thyristors, bipolar transistors, and triacs. They have hot-switching capability, are bidirectional, and support both AC and DC waveforms. Compared to solid-state relays from other manufacturers, OMRON’s G3VM relays feature single- (white) and double- (black) mold packages that give the designer the widest choice of high-sensitivity and high-dielectric-strength devices.
Omron’s G3VM MOSFET relay family includes more than 148 devices that handle a wide range of voltages and currents. Options include current limiting, high-dielectric-voltage withstand, normally open and normally closed contact forms, and high-speed switching.
