Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD230 is the BD231.The BCP56 (SOT-223) is the SMD version of the BD230 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD230 with the BD139, BD139G, BD169, BD179, BD237, BD237G, BD379, BD789, BD791, MJE242, MJE244 or MJE722.
