The KSC945G 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 KSC945CG transistor (with suffix "C") is the center collector version of the KSC945G.
Here is an image showing the pin diagram of this transistor.The KSC945G transistor can have a current gain of 200 to 400. The gain of the KSC945 will be in the range from 40 to 700, 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 KSC945G is the KSA733G.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 KSC945G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC945G with the 2N5830, 2SC1008, 2SC1008G, BC537, BC537-25, BC538, BC538-25, HS945, HS945-GR, KSC1008, KSC1008G, KSP05, KSP06, KTC9014, KTC9014C, MPS3417, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G, NTE192 or ZTX692B.
