Transient voltage suppressors (TVS) are a specialized type of semiconductor device that are specifically designed to protect electrical equipment from overvoltage transients. Varistors, also known as voltage-dependent resistors (VDRs), are commonly used for transient voltage protection. Metal oxide varistors (MOVs) are commonly used in a variety of industries as they offer superior protection for sensitive electronics from surges and ESD due to their high energy absorption capacity. The V47ZA1PX1347 is an example of an MOV that is suitable for use in a wide range of applications and is capable of handling transient voltages up to 2.5 kV.

The V47ZA1PX1347 is a multielement type MOV with two layers of zinc oxide varistor material and a glass coating. The zinc oxide varistor material absorbs surges and spikes of transient voltage and provides excellent ESD protection. Each layer is independent of the other and can be used to provide protection from overvoltage transients. The glass coating serves to protect the zinc oxide from moisture and humidity, as well as providing a more robust solution by providing additional mechanical strength and heat dissipation.

The V47ZA1PX1347 has a wide operating voltage range of 1.8 to 2.5 kV and a wide capacitance range of 0.2 to 0.7 pF. This makes it suitable for a variety of applications where protection against overvoltage transients is required. Its voltage and current handling capabilities make it suitable for use in automotive, consumer, industrial, and telecommunications applications.

The working principle of the V47ZA1PX1347 is based on a simple switching device. The two zinc oxide layers are connected to a terminal, forming a voltage divider. When a surge or spike of transient voltage is applied to the device, it acts as a switch and causes current flow between the two layers. This current flow quickly causes the voltage across the device to be drastically reduced, providing protection for the connected equipment.

The V47ZA1PX1347 is a low-cost and highly efficient transient voltage suppressor that provides excellent protection for a wide range of applications. Its wide operating voltage range makes it suitable for use in automotive, consumer, industrial, and telecommunications applications and its wide capacitance range makes it ideal for ESD protection. Its working principle of voltage division and switching makes it difficult for transients to cause damage to connected equipment, providing a robust solution for protection against overvoltage transients.
