    Have manufacturers eliminated DC SOA? Even from old devices? Can the old
    curves still be trusted, or are all new production actually broken?

    Example: compare IRF830, ST's '99 datasheet versus current Vishay docs.

    Those are essentially the same datasheet (Vishay bought IR), and don't
    include DC SOA. I suggested ST, give this a try:
    http://www.st.com/web/en/resource/technical/document/datasheet/CD00001546.pdf
    The datasheets wouldn't seem to agree, which is disturbing.
