Here is an image showing the pin diagram of this transistor.The 2SD569 transistor can have a current gain of 40 to 200. The gain of the 2SD569-K will be in the range from 100 to 200, for the 2SD569-L it will be in the range from 60 to 120, for the 2SD569-M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD569 might only be marked "D569".The complementary PNP transistor to the 2SD569 is the 2SB708.You can replace the 2SD569 with the 2SC2334, BD537, BD799, BD801, BD809, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT93, BDT93F, BDT95, BDT95F, BDX77, KSC2334, KSD569, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030 or MJF15030G.
