Here is an image showing the pin diagram of this transistor.The 2SC3205-O transistor can have a current gain of 100 to 200. The gain of the 2SC3205 will be in the range from 100 to 320, 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-O might only be marked "C3205-O".The complementary PNP transistor to the 2SC3205-O is the 2SA1273-O.The KTC4375 (SOT-89) and KTC4375O (SOT-89) is the SMD version of the 2SC3205-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KTC3205O is the TO-92 version of the 2SC3205-O.You can replace the 2SC3205-O with the 2SC2328A, 2SC2328A-O, 2SC2655, 2SD1207, 2SD1207-R, 2SD1347, 2SD1347R, 2SD1835, 2SD1835-R, KSC2328A, KSC2328A-O, KTC3205, KTC3205O, KTC3209, KTC3210 or KTC3210O.
