Zener diode is a diode which is used in its break down region. The diode is kept reverse biased in a circuit, and so it does not allow current to pass until the voltage is greater than the breakdown voltage of the zener.
breakdown voltage. (electricity). The voltage measured at a specified current in the electrical breakdown region of a semiconductor diode. Also known as Zener voltage. The voltage at which an electrical breakdown occurs in a dielectric. The voltage at which an electrical breakdown occurs in a gas. Also known as breakdown potential; sparking potential; sparking voltage.
