Here is an image showing the pin diagram of this transistor.The 2SB1009-Q transistor can have a current gain of 120 to 270. The gain of the 2SB1009 will be in the range from 82 to 390, for the 2SB1009-P it will be in the range from 82 to 180, for the 2SB1009-R it will be in the range from 180 to 390.Sometimes the "2S" prefix is not marked on the package - the 2SB1009-Q might only be marked "B1009-Q".The complementary NPN transistor to the 2SB1009-Q is the 2SD1380-Q.You can replace the 2SB1009-Q with the 2SA1214, 2SA715, 2SB1142, 2SB1143, 2SB1165, 2SB1166, 2SB744, 2SB744A, 2SB986, BD132, BD188, BD190, BD234, BD234G, BD236, BD236G, BD376, BD378, KSB744, KSB744A, MJE232, MJE235, MJE371 or MJE371G.
