The KTA1279 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, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The KST92 (SOT-23), MMBTA92 (SOT-23) and PZTA92 (SOT-223) is the SMD version of the KTA1279 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1279 with the 2SA1625, 2SA1625-K, 2SA1625-L, 2SA1625-M, 2SA1972, KSA1625, KSA1625-K, KSA1625-L, KSA1625-M, KTA1277, KTA1277O or KTA1277Y.
