TVS (Trans-Zonal Voltage Suppression devices) protect electrical and electronic circuits from high voltage transient pulses. Varistors, also known as VDRs (Voltage Dependent Resistor), are one type of TVS and are very popular for circuit protection applications. Varistors can be used in a variety of applications from providing surge protection for small telecom circuits to complete system level protection for industrial and consumer applications. V07E320PL2T is one of these devices, designed to provide reliable overvoltage protection for sensitive electronic circuits.

The V07E320PL2T is a 350V Metal Oxide Varistor (MOV) with a peak pulse power rating of up to 60kW, providing robust overvoltage protection. It is widely used in DC/DC converters and AC/DC converters and other circuits where an overvoltage transient must be prevented. It is also well-suited for power supply line protection against ESD (electrostatic discharges), surge pulses, lightning strikes, and other types of overvoltage transients.

The V07E320PL2T Varistor is made with zinc oxide material and is comprised of several discs in a ceramic housing. Its working principle is based on the voltage dependent resistor (VDR) effect, which means it has a high resistance value at low voltage and a very low resistance value when the applied voltage exceeds the Varistor’s rated nominal breakdown voltage. In addition, the device also exhibits a hysteresis effect, meaning its resistance value at the nominal breakdown voltage increases once that point has been reached.

When operating normally, the Varistor will be highly resistive, allowing very little current to pass. When an overvoltage transient occurs (such as an electrostatic discharge or surge pulse), the Varistor’s resistance quickly drops, allowing the current to flow through the device and thus protecting the circuit. At the same time, the device dissipates the surge energy, effectively limiting the voltage applied to the circuit.

The V07E320PL2T Varistor also combines this surge protection with built-in ESD protection in order to further protect against overvoltage transients. The device has an ESD rating of 8kV Human Body Model (HBM) in an air gap discharge configuration and >15kV HBM in a contact discharge configuration for increased protection performance. This makes it suitable for a wide variety of applications, from consumer electronics to automotive systems.

The V07E320PL2T Varistor has a number of features which make it a robust overvoltage protection component for many applications. It features a wide operating temperature range from -40C to +125C, and it is RoHS compliant. On top of that, it is also UL recognized and CE marked.

To sum it up, the V07E320PL2T Varistor is a versatile and robust device for overvoltage transient protection. It is widely used in DC/DC converters, AC/DC converters, and other sensitive electrical circuits. With its low leakage current, low capacitance, and wide temperature range, it provides reliable overvoltage protection for many applications, from consumer electronics to automotive systems.
