Here is an image showing the pin diagram of this transistor.The KTA1045L-Y transistor can have a current gain of 100 to 200. The gain of the KTA1045L will be in the range from 100 to 320, for the KTA1045L-GR it will be in the range from 160 to 320.The complementary NPN transistor to the KTA1045L-Y is the KTC2025L-Y.The 2SA1201 (SOT-89), 2SB806 (SOT-89), 2SB806-KR (SOT-89), 2SD1007 (SOT-89), 2SD1007-HR (SOT-89) and KTA1661 (SOT-89) is the SMD version of the KTA1045L-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1045L-Y with the 2SB905 or 2SB905-O.
