Here is an image showing the pin diagram of this transistor.The 2SC3447-M transistor can have a current gain of 20 to 40. The gain of the 2SC3447 will be in the range from 15 to 50, for the 2SC3447-L it will be in the range from 15 to 30, for the 2SC3447-N it will be in the range from 30 to 50.Sometimes the "2S" prefix is not marked on the package - the 2SC3447-M might only be marked "C3447-M".You can replace the 2SC3447-M with the 2SC3750, 2SC3750-M, 2SC3795, 2SC3795A, KSC5021, KSC5021-O, KSC5021F, KSC5021F-O, MJE8502 or MJE8503.
