Here is an image showing the pin diagram of this transistor.The 2SB703A-R transistor can have a current gain of 60 to 120. The gain of the 2SB703A will be in the range from 40 to 200, for the 2SB703A-Q it will be in the range from 100 to 200, for the 2SB703A-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SB703A-R might only be marked "B703A-R".The complementary NPN transistor to the 2SB703A-R is the 2SD743A-R.The BDP954 (SOT-223) is the SMD version of the 2SB703A-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB703A-R with the 2N6475, 2N6476, 2SA1010, 2SA1010L, 2SA1077, 2SB1016, 2SB1090, 2SB1367, 2SB595, 2SB995, BD244C, BD540C, BD544C, BD546C, BD712, BD744C, BD802, BD912, BD954, BD956, BDT86, BDT86F, BDT88, BDT88F, BDT96, BDT96F, KSA1010, KSA1010O, KTB1367, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031, MJF15031G or NTE292.
