VDRH14V050TSE

TVS - Varistors, MOVs are the most widely used in the automotive industry and in various household and industrial applications, as they are able to protect circuits against high-voltage and electronic transients or surges. One of the most popular and respected electronic components in this category is the VDRH14V050TSE (Voltage Dependent Resistor, Hermatically sealed). This device is able to reduce voltage overshoots and suppress the violent electrical discharge related to the electrical transients, thus providing an efficient ESD (Electrostatic Discharge) protection.

Application Field of VDRH14V050TSE

VDRH14V050TSE is most often used in the automotive industry and in various industrial applications, to protect sensitive electronic components from ESD transients and high-voltage spikes. Its excellent surge withstand capability and superiority in clamping performance makes it ideal for various automotive protection circuits, such as auto-start and ECUs. It is also suitable for general purpose ESD protection of electronic systems in household, IT and industrial applications.

Working Principle of VDRH14V050TSE

The VDRH14V050TSE is formed by the Metal Oxide Varistor (MOV), which functions as the main active component, along with other supporting electronic components. Its working principle is based on the Varistor effect, which is related to the nonlinear behavior of certain materials, such as Nickel, Cobalt and Zinc Oxide, that are used in manufacturing Metal Oxide Varistors. When an electrical current passes through a circuit with these materials the current will depend on the applied voltage. The energy is then dissipated through the Varistors, turning it into a harmless heat.

When an electrical transient or surge is present, the MOV will become an open switch allowing the flow of current through the circuit, thus providing an efficient and fast protection to the component or system. In addition, the VDRH14V050TSE has an excellent Durability to withstand repetitive transients enabling it to be used in high-end and sensitive automotive and industrial applications.

Conclusion

In conclusion, the VDRH14V050TSE is an excellent choice for high-voltage suppression and ESD protection. Its application field is wide, ranging from automotive, consumer electronics to industrial products, due to its excellent surge withstand capability and top-class clamping performance. Its working principle is easy to understand and is based on the Varistor effect which makes it an ideal choice for efficient ESD protection.
