Need Help Identifying Diode

[Philbot]

I repair robots in an automated warehouse in New Jersey. One of our robots uses track sensors to guide its way along a grid
and recognize intersections. The sensor itself retails for almost $500 but the part that seems to take the most abuse is what
I assume is a relatively inexpensive diode. I've searched online and even did a number of Google image searches but no no
avail. I was hoping someone might be able to help me identify the pink bubble-faced diode in the attached pics so that I can
source.
