What Is Zener Diode?

A Zener diode is a silicon semiconductor device that permits current to flow in either a 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 is reached.

How Zener diode work as voltage regulator.

• Tolerance and Type Number Designation. The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%
  
• Zener Voltage (Vz) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature(TL) at 30℃±1°C, from the diode body
• Zener Impedance (Zz) Derivation. The zener impedance is derives from the 60 cycle AC voltage, which result when an ac current having and rms value equal to 10% of the DC zener current (IZT or IZK) is superimposed on IZT or IZK
