Here is an image showing the pin diagram of this transistor.The 2SA1388-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1388 will be in the range from 70 to 240, for the 2SA1388-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1388-Y might only be marked "A1388-Y".The complementary NPN transistor to the 2SA1388-Y is the 2SC3540-Y.The BDP952 (SOT-223) and BDP954 (SOT-223) is the SMD version of the 2SA1388-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1388-Y with the 2SA1293, 2SA1293-Y, 2SA1308, 2SA1308-Y, 2SA1329, 2SA1329-Y, 2SA1452, 2SA1452-Y, 2SA1452A, 2SA1452A-Y, 2SA771, 2SB1016, 2SB1016-Y, 2SB1016A, 2SB1016A-Y, 2SB1018, 2SB1018-Y, 2SB1018A, 2SB1018A-Y, 2SB1367, 2SB1367-Y, 2SB595, 2SB595-Y, 2SB633, 2SB870, 2SB945, 2SB946, 2SB992, 2SB992-Y, 2SB995, 2SB995-Y, BD244B, BD244C, BD538, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD800, BD802, BD810, BD952, BD954, BD956, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D45H11, D45H11FP, KTA1038, KTA1038-Y, KTA1049, KTA1049Y, KTB1367, KTB1367Y, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031, MJF15031G, TTA1452B or TTB1452B.
