Here is an image showing the pin diagram of this transistor.The 2SB1140-R transistor can have a current gain of 100 to 200. The gain of the 2SB1140 will be in the range from 100 to 400, for the 2SB1140-S it will be in the range from 140 to 280, for the 2SB1140-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SB1140-R might only be marked "B1140-R".You can replace the 2SB1140-R with the 2SA1120, 2SA1357, 2SA1357-O, 2SB1127 or 2SB1127-R.
