What state should the regulator diode be in when it works normally

The regulator diode should be in a reverse breakdown state when working normally. A voltage regulator diode (also known as a Zener diode) is an area contact crystal diode made of silicon material, referred to as a voltage regulator diode. This diode is a semiconductor device with a high resistance until the critical reverse breakdown voltage.

When the regulator diode is reversed in the reverse breakdown, in a certain current range (or within a certain power loss range), the terminal voltage is almost unchanged, showing the characteristics of voltage regulation, so it is widely used in regulated power supplies and limiting circuits. regulator diode are binned according to the breakdown voltage, and because of this feature, regulator diode are mainly used as voltage regulators or voltage reference elements.
