Here is an image showing the pin diagram of this transistor.The KTA1275 transistor can have a current gain of 60 to 320. The gain of the KTA1275O will be in the range from 100 to 200, for the KTA1275R it will be in the range from 60 to 120, for the KTA1275Y it will be in the range from 160 to 320.The complementary NPN transistor to the KTA1275 is the KTC3228.The KST93 (SOT-23) is the SMD version of the KTA1275 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SA1275 is the TO-92 version of the KTA1275.You can replace the KTA1275 with the 2SA1275 or KSA1013.
