The MPS4354 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 FMMTA55 (SOT-23), KST55 (SOT-23) and MMBT4354 (SOT-23) is the SMD version of the MPS4354 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
