Here is an image showing the pin diagram of this transistor.The 2SB514D transistor can have a current gain of 60 to 120. The gain of the 2SB514 will be in the range from 40 to 320, for the 2SB514C it will be in the range from 40 to 80, 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 2SB514D might only be marked "B514D".The complementary NPN transistor to the 2SB514D is the 2SD330D.The 2SA1364 (SOT-89), 2SA1364-C (SOT-89) and BCP52 (SOT-223) is the SMD version of the 2SB514D transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB514D with the 2N6107, 2N6107G, 2N6108, 2N6109, 2N6109G, 2N6110, 2N6475, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SA1008, 2SA1008L, 2SA1010, 2SA1010L, 2SA1262, 2SA1488, 2SA1488A, 2SA1634, 2SA1634-D, 2SA1635, 2SA1635-D, 2SA1725, 2SA1726, 2SA489, 2SA614, 2SA671, 2SA671-B, 2SA748, 2SA754, 2SA754-B, 2SA755, 2SA755-B, 2SA768, 2SA769, 2SA770, 2SA771, 2SB1015, 2SB1015-O, 2SB1016, 2SB1017, 2SB1090, 2SB1097, 2SB1185, 2SB1185D, 2SB1187, 2SB1187-D, 2SB1366, 2SB1366-O, 2SB1367, 2SB1368, 2SB434, 2SB507, 2SB507D, 2SB565, 2SB565-B, 2SB566, 2SB566-B, 2SB566A, 2SB566A-B, 2SB595, 2SB596, 2SB633, 2SB633-D, 2SB703, 2SB703-R, 2SB703A, 2SB703A-R, 2SB707, 2SB707-O, 2SB708, 2SB708-O, 2SB747, 2SB747-Q, 2SB761, 2SB761A, 2SB762, 2SB762A, 2SB834, 2SB834O, 2SB857, 2SB857-B, 2SB858, 2SB858-B, 2SB870, 2SB870-R, 2SB942, 2SB942A, 2SB945, 2SB945-R, 2SB946, 2SB946-R, 2SB994, 2SB994-O, 2SB995, 2SB996, BD204, BD240A, BD240B, BD240C, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD708, BD710, BD712, BD744A, BD744B, BD744C, BD798, BD800, BD802, BD808, BD810, BD908, BD910, BD912, BD936, BD936F, BD938, BD938F, BD940, BD940F, BD950, BD952, BD954, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT92, BDT92F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSA1010, KSA1010O, KSA614, KSB1015, KSB1015-O, KSB1017, KSB1097, KSB596, KSB707, KSB707-O, KSB708, KSB708-O, KSB834, KSB834-O, KTB1366, KTB1366O, KTB1367, KTB1368, KTB988, KTB988O, NTE153 or NTE197.
