Here is an image showing the pin diagram of this transistor.The 2SB1110 transistor can have a current gain of 60 to 320. The gain of the 2SB1110-B will be in the range from 60 to 120, 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 might only be marked "B1110".The complementary NPN transistor to the 2SB1110 is the 2SD1610.The BF623 (SOT-89) and BF823 (SOT-23) is the SMD version of the 2SB1110 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB1110 with the 2SA1352, 2SA1353, 2SA1380, 2SA1381, 2SA1406, 2SA1407, 2SA1478, 2SA1479, 2SA1480, 2SA1540, 2SA1541 or KSA1381.
