Varistors, MOVs or Voltage Dependent Resistor (VDR) are an extremely important component used in many industries. The VDR14T420TME is a particular type of VDR which is designed to absorb high energy electrostatic discharges and help protect sensitive electronic equipment from any damage that may be caused by such surges. This article will discuss the application field and working principle of the VDR14T420TME.

The VDR14T420TME is a low-profile, fast response, large gap voltage device that is designed for use in high voltage, ultra-high-capacity (IEC/EN 60950 compliant) applications. It is suitable for use in electronic circuits, telecommunications systems, and other environments where high performance and reliability are required. It is suitable for power supplies, and other applications where it can replace discrete MOVs. Its application field includes but not limited to oil and gas pipelines, power plants, automobiles, solar energy systems, telecom networks, and medical equipment.

The VDR14T420TME has a unique construction among VDRs which consists of two main parts- a ceramic element and a series of metal plates. The metal plates act as the conductor for the pattern while the ceramic element provides structural stability and additional electrical insulation. The device is designed to be triggered by a voltage surge above its triggering voltage, allowing it to effectively absorb any high energy electrostatic discharges. It functions by conducting current away from the circuit due to its low clamping voltage which effectively tricks the surge energy in that component of the circuit.

Once triggered, the VDR14T420TME provides an enhanced level of protection by providing a faster response time with a steady time constant to hold the voltage at the low clamping voltage until the surge dissipates. The low clamping voltage prevents any further undesired failures while the fast response ensures the protection in time. Moreover, the device has superior surge capacity and a very low leakage current which makes it suitable for use in sensitive circuits. Its high dielectric strength is also superior to that of its predecessors.

In conclusion, the VDR14T420TME is an advanced VDR device designed to provide effective protection against high energy electrostatic discharges and other voltage surges. It is suitable for a wide range of applications and has superior surge capacity and low leakage current, making it suitable for sensitive circuits. With its high dielectric strength and high performance, the VDR14T420TME is an excellent choice for protection against voltage surges and other transient events.
