The KSC945CR 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 KSC945R.
Here is an image showing the pin diagram of this transistor.The KSC945CR transistor can have a current gain of 40 to 80. The gain of the KSC945C will be in the range from 40 to 700, for the KSC945CG it will be in the range from 200 to 400, for the KSC945CL it will be in the range from 350 to 700, for the KSC945CO it will be in the range from 70 to 140, for the KSC945CY it will be in the range from 120 to 240.The complementary PNP transistor to the KSC945CR is the KSA733CR.You can replace the KSC945CR with the 2SC2000, 2SC2000-M, BC637, BC639, KSC1008C, KSC1008CR, KSC2331 or KSC2331R.
