Here is an image showing the pin diagram of this transistor.The BD538J transistor can have a current gain of 30 to 75. The gain of the BD538 will be in the range from 40 to 0, for the BD538K it will be in the range from 40 to 100.The complementary NPN transistor to the BD538J is the BD537J.You can replace the BD538J with the 2N6491, 2N6491G, BD710, BD712, BD744B, BD744C, BD800, BD802, BD810, BD910, BD912, BDT94, BDT94F, BDT96, BDT96F, BDX78, MJF2955 or MJF2955G.
