Here is an image showing the pin diagram of this transistor.The 2SC2705 transistor can have a current gain of 80 to 240. The gain of the 2SC2705O will be in the range from 80 to 160, for the 2SC2705Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2705 might only be marked "C2705".The complementary PNP transistor to the 2SC2705 is the 2SA1145.You can replace the 2SC2705 with the 2N5551C, 2SC2229, 2SC2383, 2SC3206, 2SC3228, 2SC3467, 2SC3468, BF420, BF422, HSD1609S, KSC1506, KSC2310, KSC2330, KSC2383, KTC3206 or KTC3228.
