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

Classification of hFE

The 2SB743-P transistor can have a current gain of 160 to 320. The gain of the 2SB743 will be in the range from 60 to 320, for the 2SB743-Q it will be in the range from 100 to 200, for the 2SB743-R it will be in the range from 60 to 120.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SB743-P might only be marked "B743-P".

Complementary NPN transistor

The complementary NPN transistor to the 2SB743-P is the 2SD793-P.
