The KSP14 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 KST14 (SOT-23), MMBTA14 (SOT-23), PMBTA14 (SOT-23) and PZTA14 (SOT-223) is the SMD version of the KSP14 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSP14 with the 2N6426, 2N6427, MPSA14, MPSW13, MPSW14, MPSW45, MPSW45A, MPSW45AG or MPSW45G.
