The MPSA55G 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 MPSA55G is the MPSA05G.The BCW89 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the MPSA55G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPSA55G with the 2SA708Y, BC527-16, BC527-25, BC528-16, BC528-25, KN2907A, KSA708Y, KSP2907A, KSP8598, KSP8599, KTN2907A, MPS2907A, MPS2907AG, MPS4355, MPS8598, MPS8598G, MPS8599, MPS8599G, MPSA55, MPSA56, MPSA56G, P2N2907A, P2N2907AG, PN2905A, PN2907A, PN4355, ZTX792A, ZTX951 or ZTX953.
