Here is an image showing the pin diagram of this transistor.The 2SB772R transistor can have a current gain of 60 to 120. The gain of the 2SB772 will be in the range from 60 to 400, for the 2SB772E it will be in the range from 200 to 400, for the 2SB772GR it will be in the range from 200 to 400, for the 2SB772O it will be in the range from 100 to 200, for the 2SB772P it will be in the range from 160 to 320, for the 2SB772Q it will be in the range from 100 to 200, for the 2SB772Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SB772R might only be marked "B772R".The complementary NPN transistor to the 2SB772R is the 2SD882R.You can replace the 2SB772R with the 2N4918, 2N4918G, 2N4919, 2N4919G, 2SB743, 2SB743-R, 2SB744, 2SB744-R, 2SB744A, 2SB744A-R, BD132, BD176, BD178, BD186, BD188, BD190, BD436, BD436G, BD438, BD438G, BD440, BD440G, BD786, BD788, BD788G, KSB744, KSB744-R, KSB744A, KSB744A-R, KSB772, KSB772-R, KSE170, KSE171, KSH772, KSH772-R, MJE170, MJE170G, MJE171, MJE171G, MJE230, MJE231, MJE232, MJE233, MJE234, MJE235 or MJE370.
