Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD135G is the BD136G.The BCP54 (SOT-223) is the SMD version of the BD135G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD135G with the BD131, BD135, BD137, BD137G, BD139, BD139G, BD165, BD167, BD169, BD175, BD177, BD179, BD187, BD189, BD226, BD228, BD230, BD233, BD233G, BD235, BD235G, BD237, BD237G, BD375, BD377, BD379, BD785, BD787, BD787G, BD789, MJE225, MJE242, MJE721 or MJE722.
