Here is an image showing the pin diagram of this transistor.The KTC3206 transistor can have a current gain of 70 to 240. The gain of the KTC3206O will be in the range from 70 to 140, for the KTC3206Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC3206 is the KTA1024.The KTC4372 (SOT-89) is the SMD version of the KTC3206 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC3206 with the 2SC2229, 2SC2383, 2SC3206, 2SC3228, 2SC3467, 2SC3468, BF420, BF422, HSD1609S, KSC1506, KSC2310, KSC2330, KSC2383 or KTC3228.
