Here is an image showing the pin diagram of this transistor.The KTA1045L transistor can have a current gain of 100 to 320. The gain of the KTA1045L-GR will be in the range from 160 to 320, for the KTA1045L-Y it will be in the range from 100 to 200.The complementary NPN transistor to the KTA1045L is the KTC2025L.The 2SB806 (SOT-89) and 2SD1007 (SOT-89) is the SMD version of the KTA1045L transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1045L with the 2SB905.
