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

Classification of hFE

The 2SB744-R transistor can have a current gain of 60 to 120. The gain of the 2SB744 will be in the range from 60 to 320, for the 2SB744-O it will be in the range from 100 to 200, for the 2SB744-Y it will be in the range from 160 to 320.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SB744-R might only be marked "B744-R".

Complementary NPN transistor

The complementary NPN transistor to the 2SB744-R is the 2SD794-R.
