Here is an image showing the pin diagram of this transistor.The 2SA1156L transistor can have a current gain of 60 to 120. The gain of the 2SA1156 will be in the range from 30 to 200, for the 2SA1156K it will be in the range from 100 to 200, for the 2SA1156M it will be in the range from 40 to 80, for the 2SA1156N it will be in the range from 30 to 60.Sometimes the "2S" prefix is not marked on the package - the 2SA1156L might only be marked "A1156L".You can replace the 2SA1156L with the KSA1156, KSA1156O, KTA1703 or KTA1703-O.
