Here is an image showing the pin diagram of this transistor.The 2SB723 transistor can have a current gain of 35 to 200. The gain of the 2SB723-A will be in the range from 35 to 70, for the 2SB723-B it will be in the range from 60 to 120, 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 might only be marked "B723".The complementary NPN transistor to the 2SB723 is the 2SD753.You can replace the 2SB723 with the 2SA909.
