Here is an image showing the pin diagram of this transistor.The 2SA754-B transistor can have a current gain of 60 to 120. The gain of the 2SA754 will be in the range from 35 to 200, for the 2SA754-A it will be in the range from 35 to 70, for the 2SA754-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA754-B might only be marked "A754-B".The complementary NPN transistor to the 2SA754-B is the 2SC1418-B.The 2SA1364 (SOT-89), 2SA1364-C (SOT-89) and BCP52 (SOT-223) is the SMD version of the 2SA754-B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA754-B 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, 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, 2SB514, 2SB514D, 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.
