Thanks Kubeek,Guessing that the package is sot23 then the marking ny leads to this part http://pdf.datasheetcatalog.com/datasheet/kec/KRC231_5S.pdf
If the package is different you might be looking at a different part.
Thanks bertus,Hello,
It might be an 2SA1213 PNP transistor.
See the attached datasheet.
