Losing depth of field when I try to apply an image with alpha to a plane

Depth of Field Problem

Hi and I really sorry to bother. I want to know if there is any solution to this problem. I am trying to setup a Depth of field for a project, as you can see on the video, when I use a .png, .tag, or even and .exr as the material the Depth of field ignores the element.

I am new, so I know that is my problem no to have all the knowledge

Is there any way that can help me?
