Here is an image showing the pin diagram of this transistor.The BD375-25 transistor can have a current gain of 150 to 375. The gain of the BD375 will be in the range from 40 to 375, for the BD375-10 it will be in the range from 63 to 160, for the BD375-16 it will be in the range from 100 to 250, for the BD375-6 it will be in the range from 40 to 100.The complementary PNP transistor to the BD375-25 is the BD376-25.The 2SD1615 (SOT-89), 2SD1622 (SOT-89), 2SD1623 (SOT-89), 2SD874A (SOT-89) and FMMT619 (SOT-23) is the SMD version of the BD375-25 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD375-25 with the 2SD1348, 2SD1682, 2SD1683, 2SD1722, 2SD1723, BD131, BD187, BD189, BD233, BD233G, BD235, BD235G, BD237, BD237G, BD377, BD377-25, BD379, BD379-25, BDX35, BDX36, BDX37, MJE225 or MJE242.
