I have a USB Tester like this one:
I have connected it by mistake to a 23 volt power source and the item stopped working. When I opened the item I found that a component was burnt (See the picture below the item marked by the red square):
I found a picture of the same board with the component clearly marked V2MJ (See the picture below):
I've searched the internet and I couldn't find what is this component. Can anyone help me identify this component and if there is a replacement for it?
P.S. The board is marked with a KCX-017-20131222 marking:
