Here is an image showing the pin diagram of this transistor.The 2SA1588 transistor can have a current gain of 70 to 400. The gain of the 2SA1588-GR will be in the range from 200 to 400, for the 2SA1588-O it will be in the range from 70 to 140, for the 2SA1588-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1588 might only be marked "A1588".
