Here is an image showing the pin diagram of this transistor.The BD137-16 transistor can have a current gain of 100 to 250. The gain of the BD137 will be in the range from 40 to 250, for the BD137-10 it will be in the range from 63 to 160, for the BD137-6 it will be in the range from 40 to 100.The complementary PNP transistor to the BD137-16 is the BD138-16.The 2SC3444 (SOT-89), BCP55 (SOT-223), BCP55-16 (SOT-223), BCX55 (SOT-89), BCX55-16 (SOT-89), BSP41 (SOT-223) and BSR41 (SOT-89) is the SMD version of the BD137-16 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD137-16 with the 2SD1684, 2SD1724, 2SD1725, 2SD669, 2SD794A, BD137G, BD139, BD139-16, BD139G, BD167, BD169, BD177, BD179, BD189, BD228, BD230, BD235, BD235G, BD237, BD237G, BD377, BD377-16, BD379, BD379-16, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSE181, KSE182, MJE181, MJE181G, MJE182, MJE182G, MJE225, MJE242, MJE244, MJE721 or MJE722.
