Here is an image showing the pin diagram of this transistor.The 2SC3751-L transistor can have a current gain of 15 to 30. The gain of the 2SC3751 will be in the range from 10 to 40, for the 2SC3751-K it will be in the range from 10 to 20, for the 2SC3751-M it will be in the range from 20 to 40.Sometimes the "2S" prefix is not marked on the package - the 2SC3751-L might only be marked "C3751-L".You can replace the 2SC3751-L with the 2SC3149, 2SC3149L, 2SC3150, 2SC3150-L, 2SC3456, 2SC3456-M, 2SC3457, 2SC3457-M, 2SC3752, 2SC3752-L, 2SC3866, 2SC5353, FJPF5027, FJPF5027-R, KSC5026, KSC5026-R, KSC5027, KSC5027-R, KSC5027F, KSC5027F-R or MJE8503.
