The KTA708 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 KTA708 transistor can have a current gain of 60 to 200. The gain of the KTA708-O will be in the range from 60 to 120, for the KTA708-Y it will be in the range from 100 to 200.The complementary NPN transistor to the KTA708 is the KTC1008.The KTA1668 (SOT-89) is the SMD version of the KTA708 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SA708 is the TO-92 version of the KTA708.You can replace the KTA708 with the 2SA1283, 2SB647 or 2SB647A.
