Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the MJE244 is the MJE254.The BDP953 (SOT-223) is the SMD version of the MJE244 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MJE244 with the 2SD1725, 2SD1725-Q, 2SD1725-R, 2SD1725-R, 2SD1725-S, BD681, BD681G, BD791, MJE243 or MJE243G.
