Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SA769 might only be marked "A769".The complementary NPN transistor to the 2SA769 is the 2SC1827.The BDP952 (SOT-223) is the SMD version of the 2SA769 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA769 with the 2SA1488A, 2SA1634, 2SA1635, 2SA771, 2SB1016, 2SB1017, 2SB1367, 2SB1368, 2SB595, 2SB596, 2SB633, 2SB762A, 2SB870, 2SB942A, 2SB945, 2SB946, 2SB995, 2SB996, BD244B, BD244C, BD538, BD540B, BD540C, BD544B, BD544C, BD546B, BD546C, BD800, BD802, BD810, BD952, BD954, BD956, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D44C10, D44C11, D44C12, D45C10, D45C11, D45C12, D45H11, D45H11FP, KSB1017, KSB596, KTB1367, KTB1368, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
