Here is an image showing the pin diagram of this transistor.The 2SD1488 transistor can have a current gain of 40 to 200. The gain of the 2SD1488-P will be in the range from 100 to 200, for the 2SD1488-Q it will be in the range from 60 to 120, for the 2SD1488-R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD1488 might only be marked "D1488".
