App note: Solid-State Relays
https://www.electronics-lab.com/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 and a linear contact. No output power supply is required. App note: Solid-State Relays – [Link]
