Here is an image showing the pin diagram of this transistor.The 2SA1308-O transistor can have a current gain of 70 to 140. The gain of the 2SA1308 will be in the range from 70 to 240, for the 2SA1308-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1308-O might only be marked "A1308-O".The complementary NPN transistor to the 2SA1308-O is the 2SC3308-O.The BDP952 (SOT-223) and BDP954 (SOT-223) is the SMD version of the 2SA1308-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1308-O with the 2N6491, 2N6491G, 2SA1010, 2SA1077, 2SA1293, 2SA1293-O, 2SA1329, 2SA1329-O, 2SA1388, 2SA1388-O, 2SA1452, 2SA1452-O, 2SA1452A, 2SA1452A-O, 2SA1725, 2SA1725-P, 2SA1726, 2SA1726-P, 2SA771, 2SB1016, 2SB1016-O, 2SB1016A, 2SB1016A-O, 2SB1018, 2SB1018-O, 2SB1018A, 2SB1018A-O, 2SB1367, 2SB1367-O, 2SB595, 2SB595-O, 2SB633, 2SB708, 2SB747, 2SB870, 2SB945, 2SB946, 2SB992, 2SB992-O, 2SB995, 2SB995-O, BD244B, BD244C, BD538, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD710, BD712, BD744B, BD744C, BD800, BD802, BD810, BD910, BD912, BD952, BD954, BD956, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D45H11, D45H11FP, KSA1010, KSB708, KTA1038, KTA1038-O, KTA1049, KTA1049O, KTB1367, KTB1367O, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
