Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SA1080 might only be marked "A1080".The complementary NPN transistor to the 2SA1080 is the 2SC2530.The 2SA1518 (SOT-23), 2SA1519 (SOT-23), 2SA1520 (SOT-23), 2SA1521 (SOT-23), BC807 (SOT-23), BC807W (SOT-323) and BCX17 (SOT-23) is the SMD version of the 2SA1080 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1080 with the 2SA1262, 2SA1488, 2SA1488A, 2SA1742, 2SA1743, 2SA1744, 2SA770, 2SA771, BD202, BD204, BD240, BD240A, BD240B, BD242, BD242A, BD242B, BD244, BD244A, BD244B, BD302, BD304, BD534, BD536, BD538, BD540, BD540A, BD540B, BD544, BD544A, BD544B, BD546, BD546A, BD546B, BD738, BD796, BD798, BD800, BD808, BD810, BD948, BD950, BD952, BDT30, BDT30A, BDT30B, BDT82, BDT82F, BDT84, BDT84F, BDX78, D44C10, D44C11, D44C12, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H11, D45H11FP or D45H8.
