The KSC1009 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, base, and collector leads. The KSC1009C transistor (with suffix "C") is the center collector version of the KSC1009.
Here is an image showing the pin diagram of this transistor.The KSC1009 transistor can have a current gain of 40 to 400. The gain of the KSC1009G will be in the range from 200 to 400, for the KSC1009O it will be in the range from 70 to 140, for the KSC1009R it will be in the range from 40 to 80, for the KSC1009Y it will be in the range from 120 to 240.The complementary PNP transistor to the KSC1009 is the KSA709.The 2SC1009 is the TO-92 version of the KSC1009.You can replace the KSC1009 with the 2SC1009.
