WebJun 17, 2016 · In forward bias, Zeners look like regular diodes. That is to say that their voltage changes a lot with current and isn't very tune-able. The reverse-bias breakdown is both tune-able (which is why you can buy Zeners in all manner of voltages) and sharp. That means you can put a lot of current through it and the voltage remains relatively constant.
