The MPS6522 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 NPN transistor to the MPS6522 is the MPS6520.The BC858 (SOT-23), BC858B (SOT-23), BC858BW (SOT-323), BC858W (SOT-323), BC859 (SOT-23), BC859B (SOT-23), BC859BW (SOT-323) and BC859W (SOT-323) is the SMD version of the MPS6522 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPS6522 with the 2SA642, 2SA642G, 2SB564A, 2SB564AGR, BC317, BC317B, BC318, BC318B, BC320, BC320B, BC321, BC321B, BCX79, HS733, HS733-GR, KSA642, KSA642G, KSA733, KSA733G, KSB564A, KSB564AG, KTC9015, KTC9015C, MPS6535, MPS6651, MPS6651G, MPS6652, MPS6652G, MPS750, MPS750G, MPSW51, MPSW51A, MPSW51AG, MPSW51G, NTE193, PN200, S9015, S9015C, SS9015 or SS9015C.
