The MPSW45 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 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23) and BSP50 (SOT-223) is the SMD version of the MPSW45 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPSW45 with the MPS650, MPS650G, MPS651, MPS651G, MPSW01A, MPSW01AG, MPSW45A, MPSW45AG, MPSW45G, ZTX690B or ZTX692B.The MPSW45G transistor is the lead-free version of the MPSW45.
