Help with finding a diode


Does anyone recognize the diode with the green material on it in the middle of this picture?

Customer would need to provide a better picture, what is the board part number, description and manufacture would increase the chance of locating a part.

I’m going to guess that’s a standard diode of some type with some ferrite rings glued onto the leads. More of an assembly than a standard product, and difficult to replicate insofar as the ferrites likely don’t have any markings on them.
