The KSC945CG 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 KSC945G.
Here is an image showing the pin diagram of this transistor.The KSC945CG transistor can have a current gain of 200 to 400. The gain of the KSC945C will be in the range from 40 to 700, 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 KSC945CR it will be in the range from 40 to 80, for the KSC945CY it will be in the range from 120 to 240.The complementary PNP transistor to the KSC945CG is the KSA733CG.The 2SC1623 (SOT-23), 2SC1623-L6 (SOT-23), 2SC2412 (SOT-23), 2SC2412-R (SOT-23), 2SC2712 (SOT-23), 2SC2712-GR (SOT-23), 2SC4116 (SOT-323), 2SC4116-GR (SOT-323), 2SC4738 (SOT-23), 2SC4738-GR (SOT-23), 2SD601A (SOT-23), FJX945 (SOT-323), FJX945G (SOT-323), KSC1623 (SOT-23), KSC1623-G (SOT-23), KTC3875 (SOT-23), KTC3875GL (SOT-23), KTC3875S (SOT-23), KTC3875S-GL (SOT-23) and MMBT2484 (SOT-23) is the SMD version of the KSC945CG transistor.
