Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD792 is the BD791.The BDP954 (SOT-223) is the SMD version of the BD792 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD792 with the MJE254.
