Here is an image showing the pin diagram of this transistor.The KTA1040D-Y transistor can have a current gain of 100 to 200. The gain of the KTA1040D will be in the range from 100 to 300, for the KTA1040D-GR it will be in the range from 150 to 300.The BDP950 (SOT-223) is the SMD version of the KTA1040D-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1040D-Y with the 2SB906, 2SB906-Y, 2SB929, 2SB929A, 2SB930, 2SB930A, 2SB931, 2SB932, 2SB933, 2SB934, KTA1042D, KTA1046 or KTA1046-Y.
