Here is an image showing the pin diagram of this transistor.The 2SB600-Q transistor can have a current gain of 100 to 200. The gain of the 2SB600 will be in the range from 40 to 200, for the 2SB600-R it will be in the range from 60 to 120, for the 2SB600-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SB600-Q might only be marked "B600-Q".The complementary NPN transistor to the 2SB600-Q is the 2SD555-Q.You can replace the 2SB600-Q with the 2SA909, 2SB706A, 2SB706A-Q, 2SB723 or 2SB723-C.
