Here is an image showing the pin diagram of this transistor.The KTA1023-O transistor can have a current gain of 80 to 240. The gain of the KTA1023 will be in the range from 80 to 240, for the KTA1023-Y it will be in the range from 80 to 240.The complementary NPN transistor to the KTA1023-O is the KTC1027-O.The 2SA1201 (SOT-89) and KTA1661 (SOT-89) is the SMD version of the KTA1023-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1023-O with the 2SA1275, 2SA965, KSA1013, KSA916 or KTA1275.
