Here is an image showing the pin diagram of this transistor.The KTA1281O transistor can have a current gain of 70 to 140. The gain of the KTA1281 will be in the range from 70 to 240, for the KTA1281Y it will be in the range from 120 to 240.The complementary NPN transistor to the KTA1281O is the KTC3209O.The 2DA1213 (SOT-89), 2DA1213O (SOT-89), 2SA1213 (SOT-89), 2SA1213-O (SOT-89), 2SA1364 (SOT-89), BCP52 (SOT-223), BCP52-10 (SOT-223), BCX52 (SOT-89) and BCX52-10 (SOT-89) is the SMD version of the KTA1281O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1281O with the 2SA1020, 2SA1020O, 2SA1315 or 2SA1315-O.
