Er, Correct me if I am being stupid.... Wouldn't two reversed Zeners in parallel behave just like two reversed normal diodes in parallel. The Zener voltage only applies when the Zener is reverse biased. The one that is forward biased will conduct at normal diode voltage. Bob Ammerman RAm Systems {Original Message removed}

Whoops - I read right through that description and didn't notice what he had said - yes, the reversed zeners would need to be in series - and still wouldn't work in this circuit.
