Hey everyone, somebody has an idea of what component this can be? It's from an nvidia gpu, I tried searching in different smd marking websites for K0019 but I can't find it. I also attached a bigger picture, it's a SOT-23-5 and looks like pin 1 goes to GND. The pcie of the motherboard is also fried so I guess it was some kind of voltage peak, maybe this is a voltage regulator?

 

Bedtime reading.

Click on the 'K'
Good luck............

I would have to say its a voltage sense circuit since its related to the 5 ohm SMD power resistor

 

Coming back to say it looks like it´s a power switch EM5203AJ-02A . The marking is KQXXX where XXX is the DATE. It´s used for DDC
