Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the MJE254 is the MJE244.The BDP954 (SOT-223) is the SMD version of the MJE254 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MJE254 with the 2SB1168, 2SB1168-Q, 2SB1168-R, 2SB1168-S, 2SB1168-T, BD682, BD682G, BD792, MJE253 or MJE253G.
