Here is an image showing the pin diagram of this transistor.The KTA1042L transistor can have a current gain of 70 to 240. The gain of the KTA1042L-O will be in the range from 70 to 140, for the KTA1042L-Y it will be in the range from 120 to 240.The BDP954 (SOT-223) is the SMD version of the KTA1042L transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
