Electronic – Component identification, on USB 2.0 data lines
componentsidentificationrepair
The component i'm trying to identify is on the usb 2.0 D+ and D- lines of a nintendo switch, its got two ground connections and has the letters DUG on it.
Since it's part of a rail gun, it's very likely to be a Thyristor (Silicon Controlled Rectifier), though since there isn't an obvious gate connection, it could be a diode as well. I'm guessing the package is TO-48 or TO-65, but it's tough to be sure.

Maybe this is it, it has the markings of DUG.
