Here is an image showing the pin diagram of this transistor.The KTC3206O transistor can have a current gain of 70 to 140. The gain of the KTC3206 will be in the range from 70 to 240, for the KTC3206Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC3206O is the KTA1024O.The KTC4372 (SOT-89) and KTC4372O (SOT-89) is the SMD version of the KTC3206O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC3206O with the 2SC1473, 2SC1473A, 2SC1473AQ, 2SC1473Q, 2SC1573, 2SC1573-Q, 2SC1573A, 2SC1573A-Q, 2SC2229, 2SC2229-O, 2SC2271, 2SC2383, 2SC2482, 2SC2551, 2SC2551-O, 2SC3206, 2SC3206-O, 2SC3228, 2SC3467, 2SC3468, 2SC3941, 2SC3941-Q, BF420, BF422, HSD1609S, KSC1506, KSC1506-O, KSC2310, KSC2310-O, KSC2330, KSC2330O, KSC2383 or KTC3228.
