Here is an image showing the pin diagram of this transistor.The 2SB1230-Q transistor can have a current gain of 70 to 140. The gain of the 2SB1230 will be in the range from 50 to 140, for the 2SB1230-P it will be in the range from 50 to 100.Sometimes the "2S" prefix is not marked on the package - the 2SB1230-Q might only be marked "B1230-Q".The complementary NPN transistor to the 2SB1230-Q is the 2SD1840-Q.You can replace the 2SB1230-Q with the 2SA1302, 2SA1386, 2SA1386-P, 2SA1386A, 2SA1386A-O, 2SA1386A-P, 2SA1386A-Y, 2SA1492, 2SA1492-P, 2SA2121, 2SA2151, 2SA2151-P, 2SB1163, 2SB1231, 2SB1231-Q, 2SB1232, 2SB1232-Q, 2SB1429, BD246C, BD250C, BD746C, NTE2329 or TIP36CA.
