In a pn junction dipole at a high value of reverse bias, the current rises sharply. The value of reverse bias is known as
A pn junction diode especially designed to work only on the reverse break-down region (i.e. at a high value of the reverse bias) is called a Zener diode. The voltage across such a diode remains constant. This voltage is called the Zener voltage.
