What voltage is needed for an optocoupler to conduct

A: The input of optocouplers is defined with the forward current IF of the emitting diode and the reverse voltage which should not be exceeded. The allowable maximum alternating current voltage that can be applied between the input pins and output pins is expressed as a root mean square (rms) value. Normally, this value is guaranteed not for an unlimited period, but for a limited test. An optocoupler, also known as photocoupler or opto-isolator, is a device which can transfer an electrical signal across two galvanically-isolated circuits by way of optical coupling. Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can.
