What is diode zener symbol?

The diode zener symbol consists of a regular diode symbol with an additional line perpendicular to the cathode line. The Zener diode is a type of diode that allows current to flow in the forward direction like a normal diode, but also allows it to flow in the reverse direction when the voltage exceeds a certain value known as the breakdown voltage or Zener voltage. The Zener symbol is used to indicate the presence of a Zener diode in a circuit. It is important to note that the Zener symbol is not interchangeable with the regular diode symbol in a circuit, as they have different characteristics and functions.
