Smd code to part number

[esinior]

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

In the absence of a photo of the PCB to provide context, could it be a PNP Darlington pair with a base resistor???

Something like this, but without the C-E diode:
