Hi
i have a smd part with mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i thinks its a transistor, but i couldn't find any part number and datasheet for it, does anybody have information for that part number?
Thanks
I have a picture of it

Hi
i have a smd part with probably mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i doubt its KTB1260 PNP transistor, but in measuring with diode mode of multimeter it shows number 1.4 between emitter and collector pins and its not open circuit, and .59 from collector to base and .8 from emitter to base , and these numbers doesn't match a pnp transistor, i couldn't find any part number and datasheet for it, does anybody have information for that part number?
I've attached pics of this part
Thanks
