BZV55C18 18V Zener Diode 500mW 5% Tolerance SOD80 Package

This is the BZV55C18 Zener diode. A Zener Diode is a semiconductor device that is used to conduct current either in the forward or reverse direction. The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage (Zener voltage) is reached. Every Zener diode has a well defined reverse breakdown voltage after which it starts conducting current in reverse bias mode without getting damaged. This is known as the Zener voltage. The device has a Zener voltage of 18V and a standard tolerance on the normal Zener voltage of ±5%. This means that the Zener voltage of the diode varies by about ±5% of the actual value mentioned in practical applications.
