Here is an image showing the pin diagram of this transistor.The 2SB1507-Q transistor can have a current gain of 70 to 140. The gain of the 2SB1507 will be in the range from 70 to 280, for the 2SB1507-R it will be in the range from 100 to 200, for the 2SB1507-S it will be in the range from 140 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SB1507-Q might only be marked "B1507-Q".The complementary NPN transistor to the 2SB1507-Q is the 2SD2280-Q.You can replace the 2SB1507-Q with the 2SB1154, 2SB1508, 2SB1508-Q, 2SB1509 or 2SB1509-Q.
