Leakage current

Hello-
I've got a leakage current problem from a semiconductor switch whose leakage current is rated @ 1mA. The extra current comes all the way through an optocoupler (TLP280).
Any thoughts? Besides adding resisters or finding a less leaky switch, I have no ideas.
Thanks!

Re: Leakage current

somehow arrange the lakage current to sink (GND)

Nora,

Could post a schematic of how you're using this photocoupler.
