Photovoltaic output optoisolators use an LED input and a photovoltaic output array to transfer control signals across an electrical isolation barrier. Unlike phototransistor-output devices, they generate an isolated output voltage that can directly drive the gates of MOSFETs or other voltage-controlled devices. Common applications include solid-state relays, isolated load switches, battery systems, industrial controls, instrumentation and high-side switching circuits.
Select a photovoltaic output optoisolator by comparing isolation voltage, input forward current, open-circuit output voltage, short-circuit output current and turn-on and turn-off times. Check the required gate charge, external discharge path, creepage and clearance distances, package style and operating-temperature range. Confirm safety approvals and insulation ratings, and verify that the output voltage and switching speed are suitable for the intended MOSFET or switching element before evaluating alternatives.
