Here is an image showing the pin diagram of this transistor.The 2SA1479 transistor can have a current gain of 40 to 320. The gain of the 2SA1479-C will be in the range from 40 to 80, for the 2SA1479-D it will be in the range from 60 to 120, for the 2SA1479-E it will be in the range from 100 to 200, for the 2SA1479-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1479 might only be marked "A1479".The complementary NPN transistor to the 2SA1479 is the 2SC3789.The PMBTA92 (SOT-23) is the SMD version of the 2SA1479 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1479 with the 2SA1353, 2SA1381, 2SA1480 or KSA1381.
