I've been searching for this everywhere, i even contacted a supplier in china and he has no idea. I'm hoping someone here would recognise this component, I think it's a sot-25 / 23-5 C301.

I've looked at this part, it says "Device Marking C300", and there is no variant. I have C301 and C306 on this board, so I think it's a C30 with last digit being the variable. The 3 I think means 3v.

you misunderstand my comment
yes it does say C300 ..... what I was suggesting as a possibility is that it may be part of a family of devices C300, 301 etc


other than that I couldn't find anything so you may be out of luck unless you can get a schematic for the board

Yes, could be from the same family. I have another board with the same part, while one of the c301 is a complete short the other one isn't, even though the part before c301 have blown on both boards. There is a possibility that the other c301 has weakened but i'll give a go and see what happens.

This is guess. Put a 2s in front and it will be a transistor. You can get a data sheet by typing 2sc301 in google search. Good Luck.
