Here is an image showing the pin diagram of this transistor.The 2SA1586-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1586 will be in the range from 70 to 400, for the 2SA1586-GR it will be in the range from 200 to 400, for the 2SA1586-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1586-Y might only be marked "A1586-Y".The complementary NPN transistor to the 2SA1586-Y is the 2SC4116-Y.You can replace the 2SA1586-Y with the FJX2907A, FJX733, FJX733Y, KTN2907AU or MMST2907A.
