The KSC945L 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 KSC945CL transistor (with suffix "C") is the center collector version of the KSC945L.
Here is an image showing the pin diagram of this transistor.The KSC945L transistor can have a current gain of 350 to 700. 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 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 KSC945L is the KSA733L.The 2SC2712 (SOT-23), 2SC2712-BL (SOT-23), 2SC4116 (SOT-323), 2SC4116-BL (SOT-323), 2SC4738 (SOT-23), 2SC4738-BL (SOT-23), FJX945 (SOT-323), FJX945L (SOT-323), KTC3875 (SOT-23), KTC3875BL (SOT-23), KTC3875S (SOT-23), KTC3875S-BL (SOT-23) and PMBT6428 (SOT-23) is the SMD version of the KSC945L transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC945K is the TO-92 version of the KSC945L.You can replace the KSC945L with the HS945, HS945-BL, KSP05, KSP06, KTC9014, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G or ZTX692B.
