Here is an image showing the pin diagram of this transistor.The 2SA985A transistor can have a current gain of 60 to 320. The gain of the 2SA985A-P will be in the range from 160 to 320, for the 2SA985A-Q it will be in the range from 100 to 200, 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 might only be marked "A985A".The complementary NPN transistor to the 2SA985A is the 2SC2275A.You can replace the 2SA985A with the 2SA1006, 2SA1006A, 2SA1006B, 2SA1667, 2SA1668, 2SB547, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
