The MPSW45A 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 FMMTA05 (SOT-23), KST05 (SOT-23), MMBTA05 (SOT-23), PZTA05 (SOT-223) and SMBTA05 (SOT-23) is the SMD version of the MPSW45A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPSW45A with the MPS651, MPS651G, MPSW45AG or ZTX692B.The MPSW45AG transistor is the lead-free version of the MPSW45A.
