Here is an image showing the pin diagram of this transistor.The 2SB1085-F transistor can have a current gain of 160 to 320. The gain of the 2SB1085 will be in the range from 60 to 320, for the 2SB1085-D it will be in the range from 60 to 120, for the 2SB1085-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB1085-F might only be marked "B1085-F".The complementary NPN transistor to the 2SB1085-F is the 2SD1562-F.You can replace the 2SB1085-F with the 2SA1006, 2SA1006-P, 2SA1006A, 2SA1006A-P, 2SA1078, 2SA1667, 2SA1668, 2SA1930, 2SA985, 2SA985-P, 2SA985A, 2SA985A-P, 2SB1186, 2SB1186-F, 2SB547, BD956, BDT88, BDT88F, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
