As a quick follow-up; it looks like the UHP495 might be useful to drive the digits and/or separators of a nixie clock. The following doc discusses the 400 series part specs as 40v minimum drive and 500mA sink. So I think the UHP495 might be useful to switch digits or separators on and off, although not to the full tube voltage.
