The KSC1009C 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. Suffix "C" means center collector in KSC1009.
Here is an image showing the pin diagram of this transistor.The KSC1009C transistor can have a current gain of 40 to 400. The gain of the KSC1009CG will be in the range from 200 to 400, for the KSC1009CO it will be in the range from 70 to 140, for the KSC1009CR it will be in the range from 40 to 80, for the KSC1009CY it will be in the range from 120 to 240.The complementary PNP transistor to the KSC1009C is the KSA709C.
