Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD239C is the BD240C.The FMMT624 (SOT-23) and FZT694B (SOT-223) is the SMD version of the BD239C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD239C with the 2N6045, 2N6045G, 2N6531, 2N6532, 2N6533, 2SC2331, 2SC2331K, 2SC2331L, 2SC2331M, 2SC2334, 2SC2334K, 2SC2334L, 2SC2334M, 2SC2527, 2SC2528, 2SC3834, 2SC4153, 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SC5171, 2SD1138, 2SD1138B, 2SD1138C, 2SD1138D, 2SD1194, 2SD1195, 2SD1196, 2SD1264, 2SD1264-P, 2SD1264-Q, 2SD1264A, 2SD1264A-P, 2SD1264A-Q, 2SD1355, 2SD1355-O, 2SD1355-R, 2SD1355-Y, 2SD1407, 2SD1407-O, 2SD1407-R, 2SD1407-Y, 2SD1407A, 2SD1407A-O, 2SD1407A-R, 2SD1407A-Y, 2SD1415, 2SD1415A, 2SD1763, 2SD1763-E, 2SD1763-F, 2SD1828, 2SD1829, 2SD1830, 2SD1892, 2SD1892-P, 2SD1892-Q, 2SD2059, 2SD2059-O, 2SD2059-R, 2SD2059-Y, 2SD2241, 2SD2495, 2SD2495-O, 2SD2495-P, 2SD2495-Y, 2SD363, 2SD363-O, 2SD363-R, 2SD363-Y, 2SD401, 2SD401-G, 2SD401-O, 2SD401-R, 2SD401-Y, 2SD401A, 2SD401A-K, 2SD401A-L, 2SD401A-M, 2SD402, 2SD525, 2SD525-O, 2SD525-R, 2SD525-Y, 2SD560, 2SD560-KB, 2SD560-LB, 2SD560-MB, 2SD610, 2SD610-Q, 2SD610-R, 2SD610-S, 2SD633, 2SD743A, 2SD743A-Q, 2SD743A-R, 2SD743A-S, 2SD866A, 2SD866A-P, 2SD866A-Q, 2SD866A-R, BD539C, BD539D, BD543C, BD545C, BD649, BD651, BD901, BD939, BD939F, BD941, BD941F, BD953, BD955, BDT61B, BDT61C, BDT63B, BDT63C, BDT65B, BDT65C, BDT85, BDT85F, BDT87, BDT87F, BDW23C, BDW42, BDW42G, BDW43, BDW53C, BDW53D, BDW63C, BDW63D, BDW73C, BDW73D, BDW93C, BDW93CF, BDX33C, BDX33CG, BDX33D, BDX53C, BDX53CG, BDX53D, BDX53E, BDX53F, KSB601, KSB601-O, KSB601-R, KSB601-Y, KSC2334, KSC2334O, KSC2334R, KSC2334Y, KSD363, KSD363-O, KSD363-R, KSD363-Y, KSD401, KSD401-G, KSD401-Y, KSD560, KSD560-O, KSD560-R, KSD560-Y, KTC2018, KTC2018-O, KTC2018-Y, KTC2028, KTC2028O, KTC2028Y, KTD2059, KTD2059O, KTD2059R, KTD2059Y, KTD2061, KTD2061O, KTD2061Y, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF122, MJF122G, MJF15030, MJF15030G, MJF6388, MJF6388G, NTE375, TIP102, TIP102G, TIP112, TIP112G, TIP122, TIP122G, TIP132, TIP132G, TIP142T or TTD1415B.
