Here is an image showing the pin diagram of this transistor.The 2SB705B-R transistor can have a current gain of 60 to 120. The gain of the 2SB705B will be in the range from 40 to 200, for the 2SB705B-Q it will be in the range from 100 to 200, for the 2SB705B-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SB705B-R might only be marked "B705B-R".The complementary NPN transistor to the 2SB705B-R is the 2SD745B-R.You can replace the 2SB705B-R with the 2SA1073, 2SA909, 2SB554, 2SB600, 2SB600-R, 2SB697K, 2SB697K-D, 2SB706, 2SB706-R, 2SB706A, 2SB706A-R, 2SB722, 2SB723, 2SB723-B, MJ15012 or MJ15012G.
