Classification of hFE

The 2SC3993-M transistor can have a current gain of 20 to 40. The gain of the 2SC3993 will be in the range from 10 to 40, for the 2SC3993-K it will be in the range from 10 to 20, for the 2SC3993-L it will be in the range from 15 to 30.


Sometimes the "2S" prefix is not marked on the package - the 2SC3993-M might only be marked "C3993-M".
