    I remember an article in Silicon Chip magazine, I think, about the construction of an audio amplifier. The transistors used had an integral isolated diode for temperture compensation.

    e.g. http://www.eetimes.com/document.asp?doc_id=1272214

    EDIT: Added a link

    That's kind of what I've found but I can't find a data sheet for it any where. The board is four layer all i can find out is the gnd and vdd pins.

    The S---K logo is definitely a Sanken trademark. (in USA distributor is Allegro system)
    There have always been a slew of Sanken devices used in various consumer devices. Some of which may be slightly modified and purposely stamped with house &/or partial number meant to protect the brand. Used to come across this frequently during my time w/Consumer Electronics.
    Specific datasheets will be non-public and to make it worse, they tend to get rid of obsolete device documents rather quickly. I have archived several of their old device catalogs over the years.
    Sanken is a supplier for printer industry and that just may in fact be a version of this darlington device?--- disregard the part number and removed pin. http://www.semicon.sanken-ele.co.jp/sk_content/std01p_ds_en.pdf.
    Otherwise, it may be listed in the printers service manual---if available?
