Here is an image showing the pin diagram of this transistor.The 2SB708-R transistor can have a current gain of 40 to 80. The gain of the 2SB708 will be in the range from 40 to 200, for the 2SB708-O it will be in the range from 60 to 120, for the 2SB708-Y it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB708-R might only be marked "B708-R".The complementary NPN transistor to the 2SB708-R is the 2SD569-M.You can replace the 2SB708-R with the 2N6134, 2N6491, 2N6491G, 2SA1010, 2SA1010M, BD538, BD538K, BD710, BD712, BD744B, BD744C, BD800, BD802, BD810, BD910, BD912, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT94, BDT94F, BDT96, BDT96F, BDX78, KSA1010, KSA1010R, KSB708, KSB708-R, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031, MJF15031G, MJF2955 or MJF2955G.
