The KSC945CL 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 KSC945L.
Here is an image showing the pin diagram of this transistor.The KSC945CL transistor can have a current gain of 350 to 700. 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 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 KSC945CL is the KSA733CL.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 KSC945CL transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC945CL with the 2SC1815, 2SC1815L, 2SC2458, 2SC2458-BL, 2SC3198, 2SC3198-BL, 2SC3199, 2SC3199-BL, 2SC3330, 2SC3331, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD789, C1815, C1815BL, C945, C945BL, KSC1815, KSC1815L, KTC1006, KTC3198, KTC3198BL, KTC3199 or KTC3199BL.
