Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SA1322 might only be marked "A1322".The complementary NPN transistor to the 2SA1322 is the 2SC3335.The BF621 (SOT-89), BF623 (SOT-89), BF821 (SOT-23) and BF823 (SOT-23) is the SMD version of the 2SA1322 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1322 with the 2SA1156K, 2SA1156L, 2SA1353-D, 2SA1353-E, 2SA1353-F, 2SA1381-D, 2SA1381-E, 2SA1381-F, 2SA1479-D, 2SA1479-E, 2SA1479-F, 2SA1480-D, 2SA1480-E, 2SA1480-F, KSA1156O, KSA1156Y, KSA1381-D, KSA1381-E, KSA1381-F, KTA1703, KTA1703-O or KTA1703-Y.
