Babel diode is overheating

[scottdarch (Scott Dixon)]

This part (diode?) started to overheat on my babel :

I’m not sure what I did to damage it but the board seems functional otherwise (as long as I don’t keep it plugin in for too long). Can you tell me what this part is so I can order a replacement from Digikey?

The diode in your pic is CRS08
Its only purpose is to prevent current flow into usb connector.
Basically it can be replaced with any low-drop diode in SOD-123 package(like MBR0520).
But I bet this won’t help your Babel, as the only reason for this diode to heat up is abnormal power consumption on 5V line. This may happen due to a short somewhere or PCB contamination(which causes a short), its hard to say remotely. But just in case clean your babels with alcohol.
Also you should check the voltage on 5V line. Here is where it can be found.
