Here is an image showing the pin diagram of this transistor.The BD534J transistor can have a current gain of 30 to 75. The gain of the BD534 will be in the range from 40 to 0, for the BD534K it will be in the range from 40 to 100.The complementary NPN transistor to the BD534J is the BD533J.You can replace the BD534J with the 2N6490, 2N6490G, 2N6491, 2N6491G, BD202, BD204, BD302, BD304, BD536J, BD538J, BD706, BD708, BD710, BD744, BD744A, BD744B, BD796, BD798, BD800, BD808, BD810, BD906, BD908, BD910, BDT92, BDT92F, BDT94, BDT94F, BDX78, MJE2901T, MJE2955T, MJE2955TG, MJF2955 or MJF2955G.Same transistor is also available in:
