Hello all,
I am repairing a medical device which includes a PWM variable power supply which drives an LED. I have tested all but 2 components and the most likely culprit for the flickering LED is an opto-coupler which is available only in China.

Can anyone recommend a replacement for the component I need? It is labelled: JC817.
Here is a link to the datasheet: http://www.datasheet4u.com/download.php?id=730540

Thanks for your valuable expertise!
