Here is an image showing the pin diagram of this transistor.The STD02N transistor can have a current gain of 5000 to 20000. The gain of the STD02N-O will be in the range from 5000 to 12000, for the STD02N-Y it will be in the range from 8000 to 20000.The complementary PNP transistor to the STD02N is the STD02P.You can replace the STD02N with the STD03N.
