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