The KTC1008 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The KTC1008 transistor can have a current gain of 100 to 320. The gain of the KTC1008-GR will be in the range from 160 to 320, for the KTC1008-Y it will be in the range from 100 to 200.The complementary PNP transistor to the KTC1008 is the KTA708.The FMMT491 (SOT-23), FMMT491Q (SOT-23) and KTC4378 (SOT-89) is the SMD version of the KTC1008 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC1008 is the TO-92 version of the KTC1008.You can replace the KTC1008 with the 2SD667.
