The 2SA1082 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 2SA1082 transistor can have a current gain of 250 to 800. The gain of the 2SA1082-D will be in the range from 250 to 500, for the 2SA1082-E it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SA1082 might only be marked "A1082".The complementary NPN transistor to the 2SA1082 is the 2SC2544.The FJV992 (SOT-23) is the SMD version of the 2SA1082 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1082 with the 2SA1085, 2SA1285 or 2SA1285A.
