The MPSW55 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 MPSW55 is the MPSW05.The BCW89 (SOT-23), FMMTA55 (SOT-23), KST55 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the MPSW55 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPSW55 with the 2SA708O, 2SA708Y, BC527-10, BC527-16, BC527-25, BC528-10, BC528-16, BC528-25, KN2907A, KSA708O, KSA708Y, KSP2907A, KSP55, KSP56, KSP8598, KSP8599, KTN2907A, MPS2907A, MPS2907AG, MPS4354, MPS4355, MPS4356, MPS751, MPS751G, MPS8598, MPS8598G, MPS8599, MPS8599G, MPSA55, MPSA55G, MPSA56, MPSA56G, MPSW55G, MPSW56, MPSW56G, NTE159, P2N2907A, P2N2907AG, PN2905A, PN2907A, PN4354, PN4355, PN4356, ZTX551, ZTX554, ZTX792A, ZTX951 or ZTX953.The MPSW55G transistor is the lead-free version of the MPSW55.
