Here is an image showing the pin diagram of this transistor.The 2SC4008-G transistor can have a current gain of 250 to 500. The gain of the 2SC4008 will be in the range from 100 to 500, for the 2SC4008-E it will be in the range from 100 to 200, for the 2SC4008-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC4008-G might only be marked "C4008-G".The BDP951 (SOT-223) and BDP953 (SOT-223) is the SMD version of the 2SC4008-G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC4008-G with the 2SC1986, 2SC2075, 2SC4007, 2SC4007-G, 2SD1274, 2SD1274A, 2SD1274B, 2SD772, 2SD792, 2SD823, BD243B, BD243C, BD537, BD539B, BD539C, BD539D, BD543B, BD543C, BD545B, BD545C, BD799, BD801, BD809, BD951, BD953, BD955, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDX77, D44H11, D44H11FP, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
