Surge Suppressor Varistor Product Overview

The 20D series surge suppressor varistor is a high-performance, metal oxide semiconductor device designed to protect electronic circuits from voltage spikes and surges. Comprising zinc oxide as the primary component, this surge varistor exhibit nonlinear resistance characteristics, making them highly responsive to voltage changes. When the voltage exceeds a specific threshold, the high voltage varistor's resistance drops sharply, allowing it to absorb the excess energy and shield sensitive electronic components. The 20D series includes both the N(Standard) Series and the J(High Surge & High Energy) Series, with metal oxide varistor surge protection element diameters of 20mm, covering a wide voltage range from 18V to 1800V.

Applications of Surge Suppressor Varistor

Surge suppressor varistor is widely utilized across various fields of electronic engineering due to their effectiveness in surge protection. Common applications include:

  1. Communication Systems: Protecting telecommunication equipment from transient surges.
  2. Electrical Power Systems: Ensuring the reliability of electricity meters, distribution cabinets, and power switches.

High Voltage Varistor Specifications

The 20D series high voltage varistor is designed with the following specifications:

  • Varistor Voltage: 18V ~ 1800V
  • Max. Allowable Voltage: 10V ~ 1000V (AC), 14V ~ 1465V (DC)
  • Capacitance @ 1kHz: 320 pF ~ 28,500 pF

Surge Suppressor Varistor Dimensions

The 20D series surge varistor features a 20mm disc diameter, optimizing energy absorption while ensuring consistent performance across different voltage ratings.

Selection of Surge Varistor

When selecting a surge varistor, consider the following factors:

  1. Nominal Voltage: The typical operating voltage of the circuit.
  2. Maximum Continuous Operating Voltage (MCOV): The highest voltage the surge suppressor varistor can endure without degradation.
  3. Clamping Voltage: The peak voltage the surge varistor will allow during a surge.
  4. Energy Absorption Capacity: The maximum energy the metal oxide varistor surge protection can absorb during a transient event.
  5. Physical Size Constraints: The available space within the circuit design.

Working Principle of Surge Suppressor Varistor

In normal conditions, Surge Suppressor Varistor exhibits high impedance, ensuring they do not interfere with circuit operation. Upon detecting a transient surge voltage that exceeds their breakdown voltage, the surge varistor's impedance decreases rapidly, diverting the surge current away from sensitive components and protecting the circuit.

Surge Suppressor Varistor Naming Rules

Varistor naming typically reflects key specifications such as maximum allowable voltage and varistor voltage. For instance, the "20D" series indicates a 20mm disc diameter, followed by specific voltage ratings.Details are as below:
