Z77 Extreme4 damaged smd

Greetings,

While reseating my Coolermaster Hyper 212X I aciddentaly thorn off a smd transistor near the lower left heathsink mounting hole.
I tried to solder it back but it was no good, since it lost the lower left connector (i believe the pad also went the same way).

Would it be possible for someone to identify what type o IC is this one, so that I can find a replacement?
It reads WO4 21.
I'm in doubt if it is a NPN transistor or a Zener diode.

I can try to repair the lost pad with connective paint ...

I've attached 2 links with photos of the said component. I believe it is Q7482, but I might be mistaken.

The
 board still works fine even with this damaged component. Is it 
dangerours, for the CPU, ram and dedicated GPU, to leave it unrepaired?

Many Thanks.
