TVS (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors) and V385LA7 are three key components used to protect against transient voltages. The V385LA7 is a disc-shaped varistor suitable for use in portable electronics, consumer applications and automotive circuit protection. It is designed to suppress transients caused by electrostatic discharges, load switching, lightning strikes and other events.

The V385LA7 is a Non-linear Resistor in the form of a disc-shaped casting formed from a ceramic body with metal electrodes. It is a bi-directional, non-hysteretic device designed to provide very fast response time and clamping action when subjected to transient voltages. It can be used to protect circuits from damaging voltage transients caused by electrostatic discharge, load switching, inductive transients, and other sources.

The V385LA7 utilizes a Zinc Oxide (ZnO) non-linear resistor element to provide an effective electrical breakdown voltage. The resistance of the ZnO element decreases as the applied voltage increases. As the voltage increases above the Zener voltage, current from the protected device is diverted to the V385LA7, thus protecting the device from damage.

The working principle of the V385LA7 is simple. When the voltage across it increases above the rated Zener voltage of the device (typically in the range of 3.8V to 5.7V), the resistance of the ZnO element quickly decreases. This produces an internal clamping action that suppresses the transient voltage and prevents it from reaching the protected device. It also ensures that the current from the protected device is diverted safely away from sensitive circuitry.

The V385LA7 is used in many different applications. It is used in portable electronics, consumer applications, and automotive circuit protection. It is also used in circuit boards, power supplies, and computer systems. It is a reliable device that will protect against voltage transients and overvoltage.

The V385LA7 is a versatile device that can be used in a variety of applications. It is easy to install and use, and provides excellent protection against hazardous voltage transients. It is a reliable and cost-effective solution for many circuit protection applications.
