Here is an image showing the pin diagram of this transistor.The 2SD1716-Q transistor can have a current gain of 60 to 120. The gain of the 2SD1716 will be in the range from 60 to 200, for the 2SD1716-P it will be in the range from 100 to 200, for the 2SD1716-S it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SD1716-Q might only be marked "D1716-Q".The complementary PNP transistor to the 2SD1716-Q is the 2SB1161-Q.You can replace the 2SD1716-Q with the 2SC4388 or 2SC5359.
