The KSC945Y 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 KSC945CY transistor (with suffix "C") is the center collector version of the KSC945Y.
Here is an image showing the pin diagram of this transistor.The KSC945Y transistor can have a current gain of 120 to 240. The gain of the KSC945 will be in the range from 40 to 700, for the KSC945G it 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.The complementary PNP transistor to the KSC945Y is the KSA733Y.The 2SC1623 (SOT-23), 2SC2412 (SOT-23), 2SC2412-Q (SOT-23), 2SC2712 (SOT-23), 2SC2712-Y (SOT-23), 2SC4116 (SOT-323), 2SC4116-Y (SOT-323), 2SC4738 (SOT-23), 2SC4738-Y (SOT-23), FJX945 (SOT-323), FJX945Y (SOT-323), KSC1623 (SOT-23), KTC3875 (SOT-23), KTC3875S (SOT-23), KTC3875S-Y (SOT-23), KTC3875Y (SOT-23), MMBT2484 (SOT-23) and TMBT3904 (SOT-23) is the SMD version of the KSC945Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC945P is the TO-92 version of the KSC945Y.You can replace the KSC945Y with the 2N5830, 2SC1008, 2SC1008Y, 2SC1211, BC537, BC537-16, BC538, BC538-16, HS945, HS945-Y, KSC1008, KSC1008Y, KSP05, KSP06, KSP8098, KSP8099, KTC9014, KTC9014B, MPS651, MPS651G, MPS6717, MPS6717G, MPS8098, MPS8098G, MPS8099, MPS8099G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G or PN4033.
