Hi everybody,

I am looking for a SOT23-5 component with Code Marking GBKL.

As taking a picture don't have a really good result I draw the part.
The 5 bleu square are notches. I don't know if they correspond to the pin1 marking or to a brand mark. gbkl.jpg

Can someone tell me what is this part?

thanks

Thnaks a lot for the answer, it does look a lot like it but my part does not seems to have any unconnected pins.
I have a Si6466ADQ ( www.datasheetcatalog.org/datasheet/vishay/71182.pdf ) just near the GBKL and I have GBKL pins connected like that :
1: to an resistor and goes to another part
2 & 3 : connected with a capacitance and to S of the Si6466ADQ
4: connected to G of the Si6466ADQ
5: connected to a (decoupling) capacitance

Unless it does not matter to have G unconnected I am sceptical.
