Here is an image showing the pin diagram of this transistor.The 2SC3253-S transistor can have a current gain of 140 to 280. The gain of the 2SC3253 will be in the range from 70 to 280, for the 2SC3253-Q it will be in the range from 70 to 140, for the 2SC3253-R it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC3253-S might only be marked "C3253-S".The complementary PNP transistor to the 2SC3253-S is the 2SA1289-S.The NZT560 (SOT-223) is the SMD version of the 2SC3253-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3253-S with the 2SC1985, 2SC1986, 2SC3254, 2SC3254-S, 2SC3255, 2SC3255-S, 2SC3746, 2SC3746-S, 2SC3747, 2SC3747-S, 2SC3748, 2SC3748-S, 2SC4550, 2SC4551, 2SC4552, 2SD1274, 2SD1274A, 2SD1274B, 2SD613, 2SD823, BD203, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BD955, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDX77, D44H11, D44H11FP, D44H8, MJE15028, MJE15028G, TIP41D or TIP42D.
