Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the BD180G is the BD179G.The BDP952 (SOT-223) is the SMD version of the BD180G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD180G with the BD180, BD790, BD792, MJE252 or MJE254.
