Here is an image showing the pin diagram of this transistor.The 2SB514 transistor can have a current gain of 40 to 320. The gain of the 2SB514C will be in the range from 40 to 80, for the 2SB514D it will be in the range from 60 to 120, for the 2SB514E it will be in the range from 100 to 200, for the 2SB514F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SB514 might only be marked "B514".The complementary NPN transistor to the 2SB514 is the 2SD330.You can replace the 2SB514 with the 2SA1262, 2SA1488, 2SA1488A, 2SA770, 2SA771, 2SB507, 2SB633, BD204, BD240A, BD240B, BD240C, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD798, BD800, BD802, BD808, BD810, BD950, BD952, BD954, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8 or D45C9.
