A diode whose bar has bent ends like a letter Z.
Also known as: Breakdown diode symbol, Voltage reference diode
A Zener diode conducts backwards at a defined voltage, which is what makes it useful as a reference. Its symbol is the ordinary diode with the cathode bar bent at both ends, and the small bend is the only difference from a component that would be destroyed by the same treatment.
Denotes a diode designed to conduct in reverse at a specified breakdown voltage, used as a voltage reference or clamp.

Differs from an ordinary diode symbol only in the bent ends of the cathode bar, which is a small mark carrying a large functional difference.

A solid triangle pointing at a straight bar whose two ends are bent, one forwards and one backwards.
