Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BD795 is the BD796.The 2STF1550 (SOT-89) and 2STN1550 (SOT-223) is the SMD version of the BD795 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD795 with the 2N6043, 2N6043G, 2N6044, 2N6044G, 2N6387, 2N6387G, 2N6388, 2N6388G, 2N6530, 2SC3255, 2SC3255-Q, 2SC3255-R, 2SC3255-S, 2SC3345, 2SC3345-O, 2SC3345-Y, 2SC3346, 2SC3346-O, 2SC3346-Y, 2SC3709, 2SC3709-O, 2SC3709-Y, 2SC3709A, 2SC3709A-O, 2SC3709A-Y, 2SC3710, 2SC3710-O, 2SC3710-Y, 2SC3710A, 2SC3710A-O, 2SC3710A-Y, 2SC3748, 2SC3748-Q, 2SC3748-R, 2SC3748-S, 2SC4551, 2SC4551-K, 2SC4551-L, 2SC4551-M, 2SC4552, 2SC4552-K, 2SC4552-L, 2SC4552-M, 2SD1062, 2SD1062-Q, 2SD1062-R, 2SD1062-S, 2SD1158, 2SD1192, 2SD1277, 2SD1277-P, 2SD1277-Q, 2SD1277A, 2SD1277A-P, 2SD1277A-Q, 2SD1669, 2SD1669-Q, 2SD1669-R, 2SD1669-S, 2SD1827, BD201, BD203, BD301, BD303, BD533, BD533J, BD533K, BD535, BD535J, BD535K, BD537, BD537J, BD537K, BD543A, BD543B, BD545A, BD545B, BD643, BD645, BD647, BD797, BD799, BD807, BD809, BD895, BD895A, BD897, BD897A, BD899, BD899A, BDT63, BDT63A, BDT65, BDT65A, BDT81, BDT81F, BDT83, BDT83F, BDW39, BDW40, BDW41, BDW41G, BDW73, BDW73A, BDW73B, BDW93, BDW93A, BDW93B, BDX33, BDX33A, BDX33B, BDX33BG, BDX53, BDX53A, BDX53B, BDX53BG, BDX77, D44H11, D44H11FP, D44H8, TIP100, TIP100G, TIP101, TIP101G, TIP130, TIP130G, TIP131, TIP131G, TIP140T, TIP141T or TTC3710B.
