Here is an image showing the pin diagram of this transistor.The 2SA1370 transistor can have a current gain of 40 to 320. The gain of the 2SA1370-C will be in the range from 40 to 80, for the 2SA1370-D it will be in the range from 60 to 120, for the 2SA1370-E it will be in the range from 100 to 200, for the 2SA1370-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1370 might only be marked "A1370".The complementary NPN transistor to the 2SA1370 is the 2SC3467.You can replace the 2SA1370 with the 2SA1371 or KTA1279.
