Here is an image showing the pin diagram of this transistor.The 2SA2223 transistor can have a current gain of 40 to 140. The gain of the 2SA2223-O will be in the range from 50 to 100, for the 2SA2223-R it will be in the range from 40 to 80, for the 2SA2223-Y it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA2223 might only be marked "A2223".The complementary NPN transistor to the 2SA2223 is the 2SC6145.You can replace the 2SA2223 with the 2SA2223A.
