The ZTX458 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 PNP transistor to the ZTX458 is the ZTX558.The FMMT459 (SOT-23) and PMBTA45 (SOT-23) is the SMD version of the ZTX458 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
