The KSP55 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 KSP55 is the KSP05.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 KSP55 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSP55 with the 2SA708O, 2SA708Y, BC527-10, BC527-16, BC527-25, BC528-10, BC528-16, BC528-25, KN2907A, KSA708O, KSA708Y, KSP2907A, KSP56, KSP8598, KSP8599, KTN2907A, MPS2907A, MPS2907AG, MPS4354, MPS4355, MPS4356, MPS751, MPS751G, MPS8598, MPS8598G, MPS8599, MPS8599G, MPSA55, MPSA55G, MPSA56, MPSA56G, MPSW55, MPSW55G, MPSW56, MPSW56G, NTE159, P2N2907A, P2N2907AG, PN2905A, PN2907A, PN4354, PN4355, PN4356, ZTX551, ZTX554, ZTX792A, ZTX951 or ZTX953.
