Here is an image showing the pin diagram of this transistor.The 2SA1282 transistor can have a current gain of 150 to 800. The gain of the 2SA1282-E will be in the range from 150 to 300, for the 2SA1282-F it will be in the range from 250 to 500, for the 2SA1282-G it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SA1282 might only be marked "A1282".The complementary NPN transistor to the 2SA1282 is the 2SC3242.The 2SA1363 (SOT-89) is the SMD version of the 2SA1282 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1282 with the 2SA1282A.
