identifying part

[droidPup]

I am having trouble with an APC BackUps NS600. The unit does not charge the internal battery and I noticed a burning smell. I unplugged the unit and opened it. I notices a brown spot on one a white wire next to a power transistor which also looks like it overheated. The number on the transistor is 1G35SG. Also the numbers 75229P below that. Also there is a large F symbol to the side- is this a Fairchild Semiconductor's  logo? I tried searching for the part number 1G35SG with no luck. Is this the part number?
