Here is an image showing the pin diagram of this transistor.The 2SB1110-B transistor can have a current gain of 60 to 120. The gain of the 2SB1110 will be in the range from 60 to 320, for the 2SB1110-C it will be in the range from 100 to 200, for the 2SB1110-D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SB1110-B might only be marked "B1110-B".The complementary NPN transistor to the 2SB1110-B is the 2SD1610-B.The BF623 (SOT-89) and BF823 (SOT-23) is the SMD version of the 2SB1110-B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB1110-B with the 2SA1156, 2SA1156L, 2SA1352, 2SA1352-D, 2SA1353, 2SA1353-D, 2SA1380, 2SA1380-D, 2SA1381, 2SA1381-D, 2SA1406, 2SA1406-D, 2SA1407, 2SA1407-D, 2SA1478, 2SA1478-D, 2SA1479, 2SA1479-D, 2SA1480, 2SA1480-D, 2SA1540, 2SA1540-D, 2SA1541, 2SA1541-D, KSA1156, KSA1156O, KSA1381, KSA1381-D, KSE350, KTA1703, KTA1703-O, MJE350 or MJE350G.
