App note: Solid-State Relays
Solid-state relays introduction from Vishay, (PDF) MOSFET SSRs feature an optocoupler construction, but have a pair of MOSFETs on the output instead of a phototransistor. A pair of source-coupled MOSFETs emulate an electromechanical relay by providing bidirectional switch capability...
