Here is an image showing the pin diagram of this transistor.The 2SD1562 transistor can have a current gain of 60 to 320. The gain of the 2SD1562-D will be in the range from 60 to 120, for the 2SD1562-E it will be in the range from 100 to 200, for the 2SD1562-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD1562 might only be marked "D1562".The complementary PNP transistor to the 2SD1562 is the 2SB1085.The FMMT625 (SOT-23) is the SMD version of the 2SD1562 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1562 with the 2SC2275, 2SC2275A, 2SC2336, 2SC2336A, 2SC2528, 2SC4381, 2SC4382, 2SD1138, 2SD401, 2SD402, 2SD772, 2SD772A, 2SD792, 2SD792A, BD539D, BD955, BDT87, BDT87F, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
