Here is an image showing the pin diagram of this transistor.The MJD112 transistor is marked as "J112".The complementary PNP transistor to the MJD112 is the MJD117.The FMMT624 (SOT-23) and FZT694B (SOT-223) is the SMD version of the MJD112 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MJD112 with the MJD112G, MJD112T4, MJD112T4G, MJD122, MJD122G, MJD122T4 or MJD122T4G.The MJD112G transistor is the lead-free version of the MJD112.
