The 2SA1085-E is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SA1085-E transistor can have a current gain of 400 to 800. The gain of the 2SA1085 will be in the range from 250 to 800, for the 2SA1085-D it will be in the range from 250 to 500.Sometimes the "2S" prefix is not marked on the package - the 2SA1085-E might only be marked "A1085-E".The complementary NPN transistor to the 2SA1085-E is the 2SC2547-E.The FJV992 (SOT-23) and FJV992-E (SOT-23) is the SMD version of the 2SA1085-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1085-E with the 2SA1082, 2SA1082-E, 2SA1285, 2SA1285-G or 2SA1285A.
