TVS (Transient Voltage Suppressor) are used in a wide range of applications in order to protect sensitive electronic components and systems from damaging transients. One such protection devices are the V14H20P Varistors, they are able to protect systems from nearby electrostatic discharges (ESD), gives them exceptional immunity to surges and lightning, and eliminates the need for frequent reset/reconfiguration operations.

The V14H20P Varistor is a non-linear, voltage clamps that are specially designed to handle high energy spikes. It is composed of zinc oxide (ZnO) material that is dispersed between two electrodes. When an over-voltage transient occurs, the resistance of the varistor decreases, thus acting as a low impedance path for the spike current.

It consists of two metal plates with contacts that are separated by a ZnO material and embedded in an epoxy moulding. The epoxy moulding provides a robust and stable mechanical enclosure and a barrier to moisture. Additionally, a few zinc-oxide particles are dispersed in the ZnO material that enables the varistor to withstand fine particles contaminations. Such a configuration ensures excellent reliability and a long working life.

The V14H20P Varistor has a voltage clamping range of 1400 to 2000 volts. It has two distinct working principles, one is a peak power dissipation (PPM) and the other is a peak voltage dissipation (PVV). PPM mode is used for overloads, where the peak current is dissipated as heat, and the transient is limited to a low level. PVV mode is used for lightning applications, where the varistor absorbs the energy by a high resistance and voltage level.

The V14H20P Varistor has a compact size and is well suited for a wide range of applications. It can be used as a voltage snap for protection against shorted and open inputs, for motor control protection, for power-line protection, and for many more. Additionally, a V14H20P Varistor can be used in low-power systems such as telecommunications systems, personal computers, and consumer electronics.

In conclusion, the V14H20P Varistor provides a reliable system protection against damaging transients. This device is recommended for applications with high voltage and high current transients. It can withstand high peak power and short-term over-voltage conditions, and is suitable for both overload and lightning protection. Its robust and reliable design, along with its small size, make it a great choice for a wide variety of applications.
