TVS Varistors and MOVs are electronic components used to absorb potentially damaging electrical surges. The V14E440PL1T series varistors combine the surge protection expertise of Littelfuse with the zinc oxide technology of the V14 series. The varistors are cost-effective devices used to protect sensitive electrical circuits, such as telecommunications equipment and industrial electronics, from high-voltage transients.

Application Field

V14E440PL1T series varistors are designed specifically for protecting sensitive equipment in indoor and outdoor applications where high levels of surge protection are necessary. The product is suitable for protecting low voltage power electronic equipment across global regions from overvoltage transients. The part is rated for an operating voltage of up to 440 volts peak, and offers a nominal clamping voltage of 600 volts.

Working Principle

V14E440PL1T series varistors are comprised of a zinc oxide commonly coated with an organic binder. The device works by clamping the voltage across the component by providing a low impedance path to ground when the voltage reaches the device’s clamping voltage. This low impedance path ensures that any damaging high-voltage transient is safely diverted to ground and quickly dissipates, reducing the risk of component damage. This low impedance path also acts as a fuse, and will break down should the surge current become too high, providing additional protection for the equipment.

Performance Characteristics

The V14E440PL1T series is temperature stable, with an operating temperature of -40°C to 85°C. The device also has a varistor voltage rating of 27 volts to 1300 volts, and has a maximum peak current up to 600 A/s. The part is UL listed, meeting all applicable safety standards. The device also features a high surge energy, allowing it to absorb long duration transients.

Unique Features

V14E440PL1T series varistors are designed for maximum performance and reliability. The device features an all-zinc oxide construction, offering superior thermal stability and reliability. The part also features a built-in thermal shutoff feature that limits the current in case of an excessive surge, which provides added safety. The device is also surface mountable, making it easier to install in cramped spaces. Furthermore, the device is conformal coated, providing additional protection against environmental stress and potential harmful elements.

Conclusion

The V14E440PL1T series varistors combines a high surge energy rating and robust thermal performance with a low profile design suitable for use in indoor and outdoor applications. By using Littelfuse’s expertise in surge protection, the V14E440PL1T series provides reliable and effective protection from potentially damaging electrical transients.
