The V100RA16 is part of a family of varistors, MOVs and other Transient Voltage Suppression (TVS) devices used for electrical protection. It is a voltage-dependent addition to a circuit that will protect it from voltage transients due to events such as electrical surges, spikes, inductive switch transients, and lightning. It is effective against a broad range of ESD, EFT, and lightning transients.

Varistors, MOVs and other TVS devices have a similar construction where two electrodes are separated by a nonconductive material. In the case of the V100RA16, these two electrodes are made of zinc oxide. This material has a unique property when a voltage is applied. It will change its resistivity as the voltage increases or decreases, limiting the flow of current and protecting the connected circuit from voltage transients.

When the applied voltage is greater than the varistor’s breakdown voltage, it will conduct and allow current to flow. This limits the voltage across the varistor, allowing is to respond quickly to sudden increases in voltage. The V100RA16 has a high breakdown voltage and low leakage current, making it well-suited for use in a wide variety of applications. These applications include power supplies, motor control circuits, industrial equipment, consumer electronics, and telecommunications.

When using these devices, it’s important to remember that they will not protect against all voltage transients. A “crowbar” device such as a gas-filled tube is often used in combination with a TVS device for higher voltage protection. Additionally, TVS devices may need to be used in series as their breakdown voltage is dependent on the current flowing through them.

The V100RA16 is a versatile device, capable of protecting circuits from a wide range of transient voltage events. It’s suitable for use in a variety of applications and can offer reliable protection when combined with other devices. It is one of the most commonly used and reliable TVS devices, and is a great choice for any application where protection against a sudden change in voltage is needed.
