Here is an image showing the pin diagram of this transistor.

Classification of hFE

The 2SB601-L transistor can have a current gain of 3000 to 7000. The gain of the 2SB601 will be in the range from 2000 to 15000, for the 2SB601-K it will be in the range from 5000 to 15000, for the 2SB601-M it will be in the range from 2000 to 5000.


Sometimes the "2S" prefix is not marked on the package - the 2SB601-L might only be marked "B601-L".

Complementary NPN transistor

The complementary NPN transistor to the 2SB601-L is the 2SD560-LB.
