Here is an image showing the pin diagram of this transistor.The 2SB740-C transistor can have a current gain of 160 to 320. The gain of the 2SB740 will be in the range from 100 to 320, for the 2SB740-B it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB740-C might only be marked "B740-C".The complementary NPN transistor to the 2SB740-C is the 2SD789-C.The 2SB1115A (SOT-89), BSP31 (SOT-223), BSR31 (SOT-89), FMMT591 (SOT-23) and FMMT591Q (SOT-23) is the SMD version of the 2SB740-C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB740-C with the 2SA1382, 2SA1534A, 2SA1680, 2SA1761, 2SA684, 2SB1116, 2SB1116A, 2SB1229, 2SB647, 2SB647D, 2SB764, 2SB764-F, 2SB892, 2SB985, KSB1116, KSB1116A, KSB1116S, KTB764, KTB764-GR or NTE383.
