Here is an image showing the pin diagram of this transistor.The STD01N transistor can have a current gain of 5000 to 20000. The gain of the STD01N-O will be in the range from 5000 to 12000, for the STD01N-Y it will be in the range from 8000 to 20000.The complementary PNP transistor to the STD01N is the STD01P.You can replace the STD01N with the STD02N or STD03N.
