Here is an image showing the pin diagram of this transistor.The KTC2800-O transistor can have a current gain of 70 to 140. The gain of the KTC2800 will be in the range from 70 to 240, for the KTC2800-Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC2800-O is the KTA1700-O.You can replace the KTC2800-O with the 2SD669A.
