Here is an image showing the pin diagram of this transistor.The 2SA1479-E transistor can have a current gain of 100 to 200. The gain of the 2SA1479 will be in the range from 40 to 320, for the 2SA1479-C it 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-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1479-E might only be marked "A1479-E".The complementary NPN transistor to the 2SA1479-E is the 2SC3789-E.The BF621 (SOT-89), BF821 (SOT-23) and PMBTA92 (SOT-23) is the SMD version of the 2SA1479-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1479-E with the 2SA1156, 2SA1156K, 2SA1353, 2SA1353-E, 2SA1381, 2SA1381-E, 2SA1480, 2SA1480-E, KSA1156, KSA1156Y, KSA1381, KSA1381-E, KSE350, KTA1703, KTA1703-Y, MJE350 or MJE350G.
