The KSC945CO 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 KSC945O.
Here is an image showing the pin diagram of this transistor.The KSC945CO transistor can have a current gain of 70 to 140. 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 KSC945CL it will be in the range from 350 to 700, 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 KSC945CO is the KSA733CO.The 2SC2712 (SOT-23), 2SC2712-O (SOT-23), 2SC4116 (SOT-323), 2SC4116-O (SOT-323), 2SC4738 (SOT-23), 2SC4738-O (SOT-23), FJX945 (SOT-323), FJX945O (SOT-323), KTC3875 (SOT-23), KTC3875O (SOT-23), KTC3875S (SOT-23) and KTC3875S-O (SOT-23) is the SMD version of the KSC945CO transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC945CO with the 2SC1627, 2SC1627-O, 2SC1627A, 2SC1627A-O, 2SC1815, 2SC1815O, 2SC2000, 2SC2274, 2SC2274K, 2SC2277, 2SC2458, 2SC2458-O, 2SC2655, 2SC2655O, 2SC3198, 2SC3198-O, 2SC3199, 2SC3199-O, 2SC3243, 2SC3244, 2SC3328, 2SC3328-O, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD438, 2SD667, 2SD667A, 2SD863, BC637, BC639, C1815, C1815O, C945, C945O, KSC1008C, KSC1008CO, KSC1815, KSC1815O, KSC2331, KSC2331O, KTC3198, KTC3198O, KTC3199, KTC3199O, KTC3209, KTC3209O, KTC3227, KTC3227O or KTD863.
