I'm fixing a laptop and am trying to identify a transistor which I believe may be popped. Well I assume that's what it is. It has all three legs connected.
It is SOT-23 and marked MO5 or could be M05 (letter Oh or digit zero).
There are a couple of others onboard and I believe it's part of the power supply.
Any ideas ?
Thanks,
Jon
They generally use code numbers, not part of the actual number. There are a couple databses on line like this one to help identify SMD semis.
Are manufacturer's allowed to put whatever code they like on devices ? So is it possible to have 2 functionally different devices (on same package?) with the same code ?

Did you look at the link? It happens, quite often. OEMs don't check with each other to see if someone else is using the same code. They don't care, because it is an internal product ID for their use, so people loading pick & place machines can look at the marking and make sure they have the right part. Its not THEIR problem if you buy parts from someone else using the same code.
You have to have an idea what the part does, then look for parts using that code that would do the job.
