Here is an image showing the pin diagram of this transistor.The 2SA985A-Q transistor can have a current gain of 100 to 200. The gain of the 2SA985A will be in the range from 60 to 320, for the 2SA985A-P it will be in the range from 160 to 320, for the 2SA985A-R it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SA985A-Q might only be marked "A985A-Q".The complementary NPN transistor to the 2SA985A-Q is the 2SC2275A-Q.You can replace the 2SA985A-Q with the 2SA1006, 2SA1006-Q, 2SA1006A, 2SA1006A-Q, 2SA1006B, 2SA1006B-Q, 2SA1011, 2SA1011E, 2SA1306, 2SA1306A, 2SA1306B, 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SA1930, 2SA1964, 2SA1964-E, 2SA968, 2SA968A, 2SA968B, 2SB1186A, 2SB1186A-E, 2SB546, 2SB546A, 2SB546A-K, 2SB547, 2SB630, 2SB630-Q, 2SB861, 2SB861C, 2SB940, 2SB940-P, 2SB940A, 2SB940A-P, KSB546, KTA1659, KTA1659A, KTA968, KTA968A, KTB1369, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
