TVS (transient voltage suppressor) and Varistors (voltage dependant resistor) are the two types of electrical components which are being used increasingly in the industry today. The ZV50K1812T401N is one such component which is part of the family of products offered by professionals such as Fox Electronics.

The ZV50K1812T401N belongs to the category of TVS (transient voltage suppressors). TVS are designed to protect electronic circuits from over-voltage changes, particularly during transients, which can be caused by a high voltage spike or spike in ESD (electrostatic discharge). TVS offer a protection level defined by the clamping voltage at which they start working and remain active until the voltage goes back to a safe level. The ZV50K1812T401N is a bi-directional transistor that can be used to protect electronics systems from damaging voltage transients.

Varistors, on the other hand, are a class of voltage dependant resistors. The ZV50K1812T401N is one of many such products and is designed to provide protection to electronic systems from over voltage. It is a non-linear resistive element and is used as an arc suppressor in high voltage applications. It works by limiting the voltage applied to the circuit, effectively providing an over voltage protection. As opposed to TVS, the Varistor does not require an external power source and offers protection more quickly as it does not need to be activated.

The main application field for the ZV50K1812T401N is to provide active over-voltage protection to circuit boards. It can be used in a number of applications including: automotive, lighting, and consumer electronics, as well as in industrial, medical, and telecommunication applications. In automotive applications, it is used in power trains, safety systems, body electronics, and anti-lock braking system.

The working principle of the ZV50K1812T401N is simple. It consists of two diodes connected in anti-parallel which are used to limit the voltage flowing through the electronic device to a safe level. It is this protection which provides safety for the electronic system. When there is an overvoltage condition, the diode will switch on and provide a low impedance path for the overvoltage to travel along, limiting the voltage applied to the electronic system. The Varistor will also automatically switch off once the voltage has been reduced, removing the low impedance path and restoring normal operation.

The ZV50K1812T401N is a versatile over voltage protector and is an ideal solution for protecting electronic systems from damage due to overvoltage conditions. It can be used in a variety of applications such as automotive, lighting, consumer electronics, and industrial applications, providing active protection from overvoltage conditions.
