Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD228 is the BD229.The BCP55 (SOT-223) is the SMD version of the BD228 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD228 with the BD137, BD137G, BD139, BD139G, BD167, BD169, BD177, BD179, BD189, BD230, BD235, BD235G, BD237, BD237G, BD377, BD379, BD787, BD787G, BD789, BD791, MJE225, MJE242, MJE244, MJE721 or MJE722.
