Here is an image showing the pin diagram of this transistor.The 2SB1566-F transistor can have a current gain of 160 to 320. The gain of the 2SB1566 will be in the range from 100 to 320, for the 2SB1566-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB1566-F might only be marked "B1566-F".The complementary NPN transistor to the 2SB1566-F is the 2SD2395-F.The 2SB1123 (SOT-89), 2SB1124 (SOT-89), 2STF2360 (SOT-89), 2STN2360 (SOT-223) and BDP950 (SOT-223) is the SMD version of the 2SB1566-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB1566-F with the 2SA1262, 2SA1488, 2SA1488A, 2SA1634, 2SA1634-F, 2SA1635, 2SA1635-F, 2SA1742, 2SA1743, 2SA1744, 2SA770, 2SA771, 2SB1185, 2SB1185F, 2SB1187, 2SB1187-F, 2SB1375, 2SB1565, 2SB1565-F, 2SB507, 2SB507F, 2SB633, 2SB633-F, 2SB857, 2SB857-D, 2SB858, 2SB858-D, BD204, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BD950, BD952, BD954, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSB1366 or KSB1366-G.
