Here is an image showing the pin diagram of this transistor.The 2SB723-B transistor can have a current gain of 60 to 120. The gain of the 2SB723 will be in the range from 35 to 200, for the 2SB723-A it will be in the range from 35 to 70, for the 2SB723-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB723-B might only be marked "B723-B".The complementary NPN transistor to the 2SB723-B is the 2SD753-B.You can replace the 2SB723-B with the 2SA909.
