Hello. All good with you ? Thanks for reading my topic.
I have novice eletronic knowledge.
I have an damaged video card model EVGA GT 640.
That video card was analyzed only one component is damaged. Not damages in vcore area.
That component is melted being hard to identify. Have 6 pins ( 3 in each side ).
In image the component is between red lines.

That component is the SOT-363 , SOT-363-3 or SOT-363-6 ? both are similar ?
I see another detail about SOT being polarity ... that SOT is NPN , N-channel or P-channel ?
SOT-363 , SOT-363-3 or SOT-363-6 are only NPN ?

Thanks for reading.
Have an nice week.
