Here is an image showing the pin diagram of this transistor.The KTA1281Y transistor can have a current gain of 120 to 240. The gain of the KTA1281 will be in the range from 70 to 240, for the KTA1281O it will be in the range from 70 to 140.The complementary NPN transistor to the KTA1281Y is the KTC3209Y.The 2DA1213 (SOT-89), 2DA1213Y (SOT-89), 2SA1213 (SOT-89), 2SA1213-Y (SOT-89), 2SA1364 (SOT-89), 2SB1122 (SOT-89), 2SB1123 (SOT-89), 2SB766A (SOT-89), 2SB766A-R (SOT-89), BCP52 (SOT-223), BCP52-16 (SOT-223), BCX52 (SOT-89) and BCX52-16 (SOT-89) is the SMD version of the KTA1281Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1281Y with the 2SA1020, 2SA1020Y, 2SA1315, 2SA1315-Y, 2SA1680, 2SB1229, 2SB892, 2SB985 or KSA1281-Y.
