What is this SMD component?

I'm trying to identify the SMD component (marked as D7 with an underline) on a circuit board of an ARGB LED controller. I think it is a diode or resistor, but I'm not sure about it. Please can I get some help with identifying it?

A resistance check could determine if it's a diode. It should exhibit a different resistance in each direction. A fuse would provide a short in both directions. "D" is very commonly used as a reference designator for diodes, but that is NOT a hard and fast rule.
