Here is an image showing the pin diagram of this transistor.The 2SB986-S transistor can have a current gain of 140 to 280. The gain of the 2SB986 will be in the range from 100 to 560, for the 2SB986-R it will be in the range from 100 to 200, for the 2SB986-T it will be in the range from 200 to 400, for the 2SB986-U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SB986-S might only be marked "B986-S".The complementary NPN transistor to the 2SB986-S is the 2SD1348-S.The 2SB1123 (SOT-89), 2SB1123-S (SOT-89), 2SB1124 (SOT-89), 2SB1124-S (SOT-89) and BDP950 (SOT-223) is the SMD version of the 2SB986-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB986-S with the 2SB1143, 2SB1143-S, 2SB1165, 2SB1165-S, 2SB1166, 2SB1166-S, 2SB1168, 2SB1168-S, BD190, MJE235, MJE252 or MJE254.
