The KSC945 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 KSC945C transistor (with suffix "C") is the center collector version of the KSC945.
Here is an image showing the pin diagram of this transistor.The KSC945 transistor can have a current gain of 40 to 700. The gain of the KSC945G will be in the range from 200 to 400, for the KSC945L it will be in the range from 350 to 700, for the KSC945O it will be in the range from 70 to 140, for the KSC945R it will be in the range from 40 to 80, for the KSC945Y it will be in the range from 120 to 240.The complementary PNP transistor to the KSC945 is the KSA733.The 2SC945 is the TO-92 version of the KSC945.
