VE09P00131KDD

TVS - Varistors, MOVs

A Transient Voltage Suppressor (TVS) is an electronic component designed to protect electrical circuits from overvoltage transients. TVS devices work by either clamping or limiting the voltage, thereby protecting the devices connected to the circuit. TVS devices can be found in a variety of applications such as automotive, industrial, and consumer electronics, and are often used in conjunction with other electronic components (such as circuit breakers and fuses) for additional protection.

The VE09P00131KDD is a type of TVS device known as a Varistor (also known as a voltage-dependent resistor or VDR). Varistors are non-linear semiconductor devices that act like a variable resistor. This means that their resistance changes depending on the voltage applied to them; when the voltage exceeds the specified threshold (known as the “trip point”), the resistance of the device rapidly decreases. This has the effect of limiting or clamping the voltage applied to the circuit, thereby protecting it from voltage transients.

Varistors are typically constructed from metal-oxide materials, and their behavior is similar to that of a diode. Due to their low cost and easy installation, they are often used in a wide range of application fields such as motor control, AC/DC converters, surge protection and voltage regulation. The VE09P00131KDD is a surface-mounted varistor designed for AC & DC power lines, and is capable of providing maximum surge absorption of 130A.

In addition to varistors, there are also other types of TVS devices known as Metal-Oxide Varistors (MOVs). MOVs are also non-linear semiconductor devices, but unlike varistors, they are constructed from a combination of metal-oxide and polyester materials. This combination allows them to have a much higher surge current absorption rating than varistors, making them well suited for protecting high-current or heavy-duty applications such as motor control, power supplies, and solenoid valves. The VE09P00131KDD is also able to provide protection for such applications, with a maximum surge absorption of 130A.

In summary, the VE09P00131KDD is a form of TVS device known as a varistor, and is well suited for a variety of applications requiring surge protection or voltage regulation. Its metal-oxide construction makes it highly effective in protecting against transients, and capable of providing maximum surge absorption of 130A.
