Here is an image showing the pin diagram of this transistor.The 2SC3150 transistor can have a current gain of 10 to 40. The gain of the 2SC3150-K will be in the range from 10 to 20, for the 2SC3150-L it will be in the range from 15 to 30, for the 2SC3150-M it will be in the range from 20 to 40.Sometimes the "2S" prefix is not marked on the package - the 2SC3150 might only be marked "C3150".You can replace the 2SC3150 with the 2SC3457, 2SC3752, 2SC3866, FJPF5027, KSC5027, KSC5027F or MJE8503.
