Here is an image showing the pin diagram of this transistor.The 2SC2705O transistor can have a current gain of 80 to 160. The gain of the 2SC2705 will be in the range from 80 to 240, for the 2SC2705Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2705O might only be marked "C2705O".The complementary PNP transistor to the 2SC2705O is the 2SA1145O.You can replace the 2SC2705O with the 2N5551C, 2SC1473, 2SC1473A, 2SC1573, 2SC1573A, 2SC2229, 2SC2271, 2SC2383, 2SC3206, 2SC3228, 2SC3467, 2SC3468, 2SC3941, BF420, BF422, HSD1609S, KSC1506, KSC2310, KSC2330, KSC2383, KTC3206 or KTC3228.
