Here is an image showing the pin diagram of this transistor.The 2SC3205 transistor can have a current gain of 100 to 320. The gain of the 2SC3205 will be in the range from 100 to 320, for the 2SC3205-O it will be in the range from 100 to 200, for the 2SC3205-Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC3205 might only be marked "C3205".The complementary PNP transistor to the 2SC3205 is the 2SA1273.The KTC4375 (SOT-89) is the SMD version of the 2SC3205 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KTC3205 is the TO-92 version of the 2SC3205.You can replace the 2SC3205 with the 2SC2328A, 2SD1207, 2SD1347, 2SD1835, KSC2328A, KTC3205 or KTC3210.
