    Hi all,

    How much (max) DC voltage does optocoupler 4N25 isolate? I tried to look for it in its datasheet, I just could find the AC voltage rating.


    Thanx All..

    Page 3 of the datasheet says 2500 VRMS.

    Hello,

    I would keep the max DC at 500 Volts.
    See screencap of the electrical specs.
