TVS (Transient Voltage Suppressor) devices are designed to thwart electrical overpressure and overcurrent conditions in electrical and electronic systems. They are used to protect sensitive devices from voltage transient surges often caused by lightning strikes and electrostatic discharges.TVS devices such as the ERZ-V07D180 are commonly known as Varistors (Voltage Dependent Resistors) or MOVs (Metal Oxide Varistors). These devices are passive, non-linear, bidirectional components, which can be used to protect against overvoltages by clamping the voltage across its terminals. These devices can also be used as snubbers and transorb networks.

The ERZ-V07D180 Varistor from Panasonic is a non-illuminated device that helps to reduce overvoltages in a number of different applications. This device offers an excellent combination of fast response time and low capacitance, making it an ideal choice for high frequency protection applications. It also has a wide operating temperature range from -50°C to 125°C.

The working principle of the ERZ-V07D180 Varistor is based on voltage dependent resistance (VDR). When the voltage across the Varistor reaches a certain threshold, the resistance changes sharply and the transient voltage is clamped to a maximum value. This maximum value is referred to as the Varistor Voltage or V_m.

As the voltage increases, the resistance of the Varistor decreases until the Varistor Voltage is reached, where the Varistor\'s resistance becomes zero. At this point, the Varistor will conduct current until the terminal voltage is reduced below the Varistor Voltage. This provides fast response time and low capacitance during the transient surge, protecting sensitive devices that would otherwise be damaged.

The ERZ-V07D180 Varistor is typically used in a wide range of commercial, residential, automotive and industrial applications. It is commonly used in high frequency applications such as automotive systems and power supplies, where it can provide effective protection against transients, surges, and voltage spikes. It is also very useful in protecting against damage from high-amperage overloads.

The ERZ-V07D180 Varistor is a reliable low capacitance, fast response device that offers an excellent combination of properties to protect critical components in many types of applications. Its wide operating temperature range, low capacitance, and fast response make it an ideal choice for applications where protection against electrical transients and voltage surges is essential.
