Here is an image showing the pin diagram of this transistor.The 2SB435-Y transistor can have a current gain of 120 to 240. The gain of the 2SB435 will be in the range from 40 to 240, for the 2SB435-O it will be in the range from 70 to 140, for the 2SB435-R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SB435-Y might only be marked "B435-Y".The complementary NPN transistor to the 2SB435-Y is the 2SD235-Y.The 2DA1213 (SOT-89), 2DA1213Y (SOT-89), 2SA1213 (SOT-89), 2SA1213-Y (SOT-89) and BDP948 (SOT-223) is the SMD version of the 2SB435-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB435-Y with the 2SA1012, 2SA1012Y, 2SA1262, 2SA1279, 2SA1279-Y, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1293, 2SA1293-Y, 2SA1307, 2SA1307-Y, 2SA1308, 2SA1308-Y, 2SA1328, 2SA1328-Y, 2SA1329, 2SA1329-Y, 2SA1388, 2SA1388-Y, 2SA1451, 2SA1451-Y, 2SA1451A, 2SA1451A-Y, 2SA1452, 2SA1452-Y, 2SA1452A, 2SA1452A-Y, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1742, 2SA1743, 2SA1744, 2SA1869, 2SA1869Y, 2SA1931, 2SA489, 2SA489-Y, 2SA490, 2SA490-Y, 2SA614, 2SA614Y, 2SA768, 2SA769, 2SA770, 2SA771, 2SB1017, 2SB1017-Y, 2SB1018, 2SB1018-Y, 2SB1018A, 2SB1018A-Y, 2SB1019, 2SB1019-Y, 2SB1133, 2SB1134, 2SB1135, 2SB1136, 2SB1185, 2SB1187, 2SB1274, 2SB1368, 2SB1368-Y, 2SB1375, 2SB1548, 2SB1548-P, 2SB1548A, 2SB1548A-P, 2SB1565, 2SB1566, 2SB434, 2SB434Y, 2SB507, 2SB553, 2SB553-Y, 2SB596, 2SB596-Y, 2SB761, 2SB761-P, 2SB761A, 2SB761A-P, 2SB762, 2SB762-P, 2SB762A, 2SB762A-P, 2SB824, 2SB825, 2SB826, 2SB834, 2SB857, 2SB858, 2SB870, 2SB941, 2SB941-P, 2SB941A, 2SB941A-P, 2SB942, 2SB942-P, 2SB942A, 2SB942A-P, 2SB943, 2SB944, 2SB945, 2SB946, 2SB947A, 2SB948A, 2SB953A, 2SB992, 2SB992-Y, 2SB993, 2SB993-Y, 2SB996, 2SB996-Y, BD202, BD204, BD242, BD242A, BD242B, BD244, BD244A, BD244B, BD302, BD304, BD534, BD536, BD538, BD540, BD540A, BD540B, BD544, BD544A, BD544B, BD546, BD546A, BD546B, BD738, BD796, BD798, BD800, BD808, BD810, BD934, BD934F, BD936, BD936F, BD938, BD938F, BD948, BD950, BD952, BDT82, BDT82F, BDT84, BDT84F, BDX78, D44C10, D44C11, D44C12, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSA614, KSA614Y, KSB1017, KSB1017-Y, KSB1366, KSB596, KSB596-Y, KTA1036, KTB1368, KTB1368Y, KTB988, TTA1452B or TTB1452B.
