Which power do you refer to? On the input side (LED), output side (if an IC-coupler is used)?
Which data rate do you need.
dissipation between 10 to 30mW is required
You should have stated this additional requirement in your first post. We can't guess your requirements.
Please state all your requirements.

already googled.....found many
4.th hit in my search: This coupler has an input power dissipation of 20.5 mW worst case. Where did you look?

external clearance can be reduced upto 4mm
That's quite a difference to the 8 mm from your post #1. How come? Are you sure that's covered by EN60079-11 in your application?
