Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC2528 might only be marked "C2528".The complementary PNP transistor to the 2SC2528 is the 2SA1078.The FMMT625 (SOT-23) is the SMD version of the 2SC2528 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2528 with the 2SC4381, 2SC4382, 2SD401, 2SD402, 2SD772, 2SD772A, 2SD792, 2SD792A, BD539D, BD955, BDT87, BDT87F, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
