Classification of hFE

The 2SC4429 transistor can have a current gain of 10 to 40. The gain of the 2SC4429-L will be in the range from 10 to 20, for the 2SC4429-M it will be in the range from 15 to 30, for the 2SC4429-N it will be in the range from 20 to 40.


Sometimes the "2S" prefix is not marked on the package - the 2SC4429 might only be marked "C4429".
