Zener diodes (20V)

Explore our comprehensive range of Zener Diodes, essential electronic components for voltage regulation and circuit protection. Indispensable in numerous applications, Zener diodes are designed to maintain a constant voltage across their terminals when reverse-biased and the voltage reaches their breakdown threshold (Zener voltage).

Our Zener diodes offer reliable performance and exceptional stability, ensuring the longevity and efficiency of your assemblies. Whether you are an electronics professional, a student, or a DIY enthusiast, you will find the Zener diode perfectly suited to your specific needs.

Typical Applications:

  • Voltage Regulation: Ideal for stabilizing output voltage in power supplies.
  • Voltage References: Used to provide a stable reference voltage in measurement and control circuits.
  • Overvoltage Protection: Protect sensitive components by clipping voltage peaks.
  • Signal Clipping: Allow limiting the amplitude of signals in audio or signal processing applications.

How to choose your Zener diode?

Consider the following key parameters:

  • Zener Voltage (Vz): The desired regulation voltage.
  • Power Dissipation (Pz): The diode's capacity to handle power.
  • Tolerance: The precision of the Zener voltage.
  • Package Type: For easy integration into your circuits (SMD, through-hole, etc.).

Browse our carefully selected range of high-quality Zener diodes, available in a wide spectrum of voltages and power ratings. Trust our expertise for your electronic projects and ensure the reliability of your systems with high-performance components.
