Thinking about it a bit more- the closest approximation I can come up
with would be four 30v zeners in a serial-parallel combo. Two zeners in
series with anodes together in parallel with two zeners in series with
cathodes together. This would drop 30.6 ish volts in either direction if
I'm not mistaken.



Just two zeners in series with the anodes together

Or cathodes together, either way.

would do this.

You're right :-) Too late at night and too much beer for thinking!
