Here is an image showing the pin diagram of this transistor.The 2SC3117-S transistor can have a current gain of 140 to 280. The gain of the 2SC3117 will be in the range from 100 to 400, for the 2SC3117-R it will be in the range from 100 to 200, for the 2SC3117-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SC3117-S might only be marked "C3117-S".The complementary PNP transistor to the 2SC3117-S is the 2SA1249-S.You can replace the 2SC3117-S with the 2SC3902, 2SC3902-S or TTC004B.
