Here is an image showing the pin diagram of this transistor.The KTA1281 transistor can have a current gain of 70 to 240. The gain of the KTA1281O will be in the range from 70 to 140, for the KTA1281Y it will be in the range from 120 to 240.The complementary NPN transistor to the KTA1281 is the KTC3209.The 2DA1213 (SOT-89), 2SA1213 (SOT-89), 2SA1364 (SOT-89), BCP52 (SOT-223) and BCX52 (SOT-89) is the SMD version of the KTA1281 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1281 with the 2SA1020 or 2SA1315.
