Here is an image showing the pin diagram of this transistor.The 2SC3256 transistor can have a current gain of 70 to 280. The gain of the 2SC3256-Q will be in the range from 70 to 140, for the 2SC3256-R it will be in the range from 100 to 200, for the 2SC3256-S it will be in the range from 140 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SC3256 might only be marked "C3256".The complementary PNP transistor to the 2SC3256 is the 2SA1292.You can replace the 2SC3256 with the BD245A, BD245B, BD245C, BD249A, BD249B, BD249C or TIP35CA.
