Here is an image showing the pin diagram of this transistor.The 2SA1009A-H transistor can have a current gain of 100 to 200. The gain of the 2SA1009A will be in the range from 20 to 200, for the 2SA1009A-J it will be in the range from 60 to 120, for the 2SA1009A-K it will be in the range from 40 to 80, for the 2SA1009A-L it will be in the range from 30 to 60, for the 2SA1009A-M it will be in the range from 20 to 40.Sometimes the "2S" prefix is not marked on the package - the 2SA1009A-H might only be marked "A1009A-H".You can replace the 2SA1009A-H with the MJE5852 or MJE5852G.
