Here is an image showing the pin diagram of this transistor.The BD534 transistor can have a current gain of 40 to 0. The gain of the BD534J will be in the range from 30 to 75, for the BD534K it will be in the range from 40 to 100.The BD534 transistor is marked as "BD534".The complementary NPN transistor to the BD534 is the BD533.The 2STF2550 (SOT-89) and 2STN2550 (SOT-223) is the SMD version of the BD534 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BD534 with the 2N6040, 2N6040G, 2N6041, 2N6041G, 2N6667, 2N6667G, 2N6668, 2N6668G, 2SA1291, 2SA1291-Q, 2SA1291-R, 2SA1291-S, 2SA1328, 2SA1328-O, 2SA1328-Y, 2SA1329, 2SA1329-O, 2SA1329-Y, 2SA1451, 2SA1451-O, 2SA1451-Y, 2SA1451A, 2SA1451A-O, 2SA1451A-Y, 2SA1452, 2SA1452-O, 2SA1452-Y, 2SA1452A, 2SA1452A-O, 2SA1452A-Y, 2SA1471, 2SA1471-Q, 2SA1471-R, 2SA1471-S, 2SA1743, 2SA1743-K, 2SA1743-L, 2SA1743-M, 2SA1744, 2SA1744-K, 2SA1744-L, 2SA1744-M, 2SB1136, 2SB1136-Q, 2SB1136-R, 2SB1136-S, 2SB1225, 2SB826, 2SB826-Q, 2SB826-R, 2SB826-S, 2SB882, 2SB951, 2SB951-P, 2SB951-Q, 2SB951A, 2SB951A-P, 2SB951A-Q, BD536, BD536K, BD538, BD538K, BD544A, BD544B, BD546A, BD546B, BD644, BD646, BD648, BD896, BD896A, BD898, BD898A, BD900, BD900A, BDT62, BDT62A, BDT64, BDT64A, BDT82, BDT82F, BDT84, BDT84F, BDW44, BDW45, BDW46, BDW46G, BDW74, BDW74A, BDW74B, BDW94, BDW94A, BDW94B, BDX34, BDX34A, BDX34B, BDX34BG, BDX54, BDX54A, BDX54B, BDX54BG, D45H11, D45H11FP, D45H8, TIP105, TIP105G, TIP106, TIP106G, TIP135, TIP135G, TIP136, TIP136G, TIP145T, TIP146T, TTA1452B or TTB1452B.Same transistor is also available in:
