I assumed it would be emitter to collector voltage ? If so, 4n25 is listed at 6V max. Do you have any personal experiance using these at 24V ? thanks

Oct 14, 2008 #4 G Guest Guest 6 volts in 4n25 is max reverse voltage in light emitting diode , and the collector to emmiter max voltage is VCEO=30V , and reverse VECO = 6V Greetings Dragan
