TVS - Varistors, MOVs are featured by their ability to react immediately to highvoltagespikes, and thus suppress these transients. This is accomplished through their abilityto conduct current in case of an overvoltage or overcurrent.

One such type of transient voltage suppressor is the VDRS07H350TME, a 350 Volt, 600W,Radial Lead Varistor. This surge protection device is designed to protect electronic circuitsfrom transients through it’s ability to conduct a high amount of current in case of overvoltageor overcurrent conditions.

VDRS07H350TME Varistor has a working range of 350V, with a transient currentrating of 10kA. This erosion-resistant varistor is equipped with a thermally conductivelayer which helps disperse the heat generated during surge conditions. This device is lead-freesoldered, which makes them RoHS compliant. Its radial leads also mean that it is designedfor easy installation in a circuitboard.

VDRS07H350TME Application Field and Working Principle

The VDRS07H350TME Varistor is suitable for many different applications and has a variety ofadvantages for the user. Due to its radial lead design, it is ideal for use in many automatedor semi-automated circuit board assembly processes, and because it is lead-free, it complieswith the RoHS Directive.

In terms of application, the VDRS07H350TME Varistor is suitable for use on high voltage lineswhere protection from transient overvoltage and overcurrent conditions is a priority.It is suitable for use in a range of shore power applications including switch mode powersupplies, direct current to alternating current converters, power distribution systems,marine applications and any other area which may be prone to transient overvoltage or overcurrent spikes.

In terms of working principle, the VDRS07H350TME Varistor functions by always ensuring amechanical contact between the device and the circuit board. This mechanical contact helps toensure that the heat generated by the suppressor can be dispersed quickly. Additionally,the device functions by shunting the majority of any high voltage spikes away from thecircuit board. The device works by changing the resistance of its contact, which results inthe surge voltage being dissipated by the device itself.

The VDRS07H350TME Varistor also has the ability to self-latch in the event of an overvoltage or overcurrent condition. This means that it will not reset itself in between the twodifferent events, thus ensuring that the circuit board is protected during multiple spikes.

VDRS07H350TME Varistor is a highly reliable and cost effective solution for the protectionof electronic circuits from overvoltage or overcurrent conditions. It is designed for easyinstallation on circuit boards as well as many other applications, and helps provide effectiveprotection from high voltage transients.
