Default selection of optocoupler.

Hi...
I am working on design where i need to select an optocoupler.
This should operate at voltage as high as 60V. So what parameter should i consider when selecting it. Is the collector base voltage to be considered or collector emitter voltage to be considered. I have gone thorugh MCT-2E's datasheet. Is it appropriate to use.

Please suggest

Vasu

Collector-emitter voltage is what matters, many optos don't even expose the base and just bias it internally. The MCT-2E will not work in your application.
