Omron G3VM Series Solid State Relay, 4 A Load, Surface Mount, 30 V Load | G3VM-31DR(TR05)

The Omron MOSFET relays in DIP 4-pin packages that achieve the low ON resistance and high switching capacity of a mechanical relay. These MOSFET relays offer great I/O isolation due to its operational principle. It turns the voltage into the light and transfers by the light signal, Therefore input and output are isolated. The standard models offer 2,500 Vrms between input and output. Superior 5,000 VAC products are also available. 3,750 VAC products have also been added to the SOP package series. As MOSFET Relays do not have mechanical contacts, by using a MOSFET instead of an electromechanical relay, it is possible to eliminate switching noise in your applications. Comparing with the triac, MOS FET greatly reduces the dead zone. The input waveform of micro analog signal does not suffer distortion as it does with a triac and is basically converted into output waveform without distortion.
