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

Classification of hFE

The 2SB633 transistor can have a current gain of 40 to 320. The gain of the 2SB633-C will be in the range from 40 to 80, for the 2SB633-D it will be in the range from 60 to 120, for the 2SB633-E it will be in the range from 100 to 200, for the 2SB633-F it will be in the range from 160 to 320.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SB633 might only be marked "B633".

Complementary NPN transistor

The complementary NPN transistor to the 2SB633 is the 2SD613.

SMD Version of 2SB633 transistor

The BDP954 (SOT-223) is the SMD version of the 2SB633 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
