The MPS6561 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the MPS6561 is the MPS6563.You can replace the MPS6561 with the MPS3706, MPS6532, MPS6601, MPS6601G, MPS6602 or MPS6602G.
