The MPSW51 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 MPSW51 is the MPSW01.The 2SA1036 (SOT-23), 2SA1036-P (SOT-23), 2SA1036-Q (SOT-23), 2SA1036-R (SOT-23), BCW67 (SOT-23), BCW67A (SOT-23), BCW67B (SOT-23) and BCW67C (SOT-23) is the SMD version of the MPSW51 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPSW51 with the BC527-10, BC527-16, BC527-25, MPS4355, MPS750, MPS750G, MPS751, MPS751G, MPSW51A, MPSW51AG, MPSW51G, MPSW63, MPSW64, ZTX549, ZTX550, ZTX790A, ZTX949 or ZTX951.The MPSW51G transistor is the lead-free version of the MPSW51.
