An optocoupler has an isolation source voltage VISO) rating of 5200 Vac. This rating means that
A) the device can handle a 5200 Vac input.
B) the device can provide an output voltage as high as 5200 Vac.
C) 5200 Vac applied across the input/output terminals of the device will destroy the component.
D) the device can be used to drive a 5200 Vac load.

Question

Quizplus · Accepted Answer

The isolation source voltage (V_ISO) rating of an optocoupler indicates the maximum voltage that can be applied across its input and output terminals without causing breakdown or damage. Thus, applying 5200 Vac across the input/output terminals will exceed this rating and potentially destroy the component.
