The M8050 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 M8050 transistor can have a current gain of 120 to 300. The gain of the M8050-C will be in the range from 120 to 200, for the M8050-D it will be in the range from 160 to 300.The complementary PNP transistor to the M8050 is the M8550.The FMMT449 (SOT-23) is the SMD version of the M8050 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the M8050 with the 2SD471A, KSD471A, MPS650, MPS650G, MPS6601, MPS6601G, MPS6602, MPS6602G, MPS8050, MPSW01, MPSW01A, MPSW01AG, MPSW01G, PN2222A, SS8050, ZTX449 or ZTX450.
