Here is an image showing the pin diagram of this transistor.The 2SB1109-C transistor can have a current gain of 100 to 200. The gain of the 2SB1109 will be in the range from 60 to 320, for the 2SB1109-B it will be in the range from 60 to 120, for the 2SB1109-D it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SB1109-C might only be marked "B1109-C".The complementary NPN transistor to the 2SB1109-C is the 2SD1609-C.The HSB1109S-C is the TO-92 version of the 2SB1109-C.You can replace the 2SB1109-C with the 2SA1142, 2SA1142Q, 2SA1209, 2SA1209-R, 2SA1210, 2SA1210-R, 2SA1220A, 2SA1220A-Q, 2SA1248, 2SA1248-R, 2SA1249, 2SA1249-R, 2SA1352, 2SA1352-E, 2SA1353, 2SA1353-E, 2SA1380, 2SA1380-E, 2SA1381, 2SA1381-E, 2SA1406, 2SA1406-E, 2SA1407, 2SA1407-E, 2SA1477, 2SA1477-R, 2SA1478, 2SA1478-E, 2SA1479, 2SA1479-E, 2SA1480, 2SA1480-E, 2SA1507, 2SA1507-R, 2SA1540, 2SA1540-E, 2SA1541, 2SA1541-E, 2SA795A, 2SB1110, 2SB1110-C, 2SB649A, 2SB649A-C, HSB1109, HSB1109-C, KSA1142, KSA1142O, KSA1220A, KSA1220A-O, KSA1381, KSA1381-E, KSE350, KTA1700, MJE350 or MJE350G.
