Here is an image showing the pin diagram of this transistor.The 2SB1230 transistor can have a current gain of 50 to 140. The gain of the 2SB1230-P will be in the range from 50 to 100, for the 2SB1230-Q it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SB1230 might only be marked "B1230".The complementary NPN transistor to the 2SB1230 is the 2SD1840.You can replace the 2SB1230 with the 2SA1386, 2SA1386A, 2SA1386A-O, 2SA1386A-P, 2SA1386A-Y, 2SA1492, 2SA2151, 2SB1231, 2SB1232, BD246C, BD250C, BD746C or TIP36CA.
