    Depends upon your application.

    The ZTX458/558 form complementary transistors rated at 400 volts. If you need this your alternative choices are rather limited.

    For slightly less try the MPSA45/94.
    Ratings are

    ZTX
    Vce =400
    Ic=1000mA
    P=1000mW

    MPSA
    Vce =400 for MPSA94, 350 for MPSA45
    Ic=300mA
    P=625mW
