The KTA539 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 KTA539 transistor can have a current gain of 70 to 240. The gain of the KTA539-O will be in the range from 70 to 240, for the KTA539-Y it will be in the range from 70 to 240.The complementary NPN transistor to the KTA539 is the KTC815.The 2SA1483 (SOT-89) and FJX733 (SOT-323) is the SMD version of the KTA539 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SA539 is the TO-92 version of the KTA539.You can replace the KTA539 with the 2SA539, 2SA697, 2SA708, BC527, BC528, KSA539, KSA708, KSP55, KSP56, MPS4354, MPS4356, MPSW55, MPSW55G, MPSW56, MPSW56G, NTE159, PN4354 or PN4356.
