• SIOV® Metal Oxide Varistors | EPCOS

Despite its many benefits, one of the few drawbacks of semiconductor technology is the vulnerability of solid-state devices to overvoltages. Even voltage pulses of very low energy can produce interference and damage, sometimes with far-reaching consequences. So, as electronics makes its way into more and more applications, optimum overvoltage or transient suppression becomes a design factor of decisive importance.
SIOV® varistors have proven to be excellent protective devices because of their application flexibility and high reliability. The metal oxide varistor, with its extremely attractive price/performance ratio, is an ideal component for limiting surge voltage and current as well as for absorbing energy. The EPCOS product range includes radial-leaded disks, block varistors and strap varistors for power distribution applications. Special types for automotive electrical systems and for telecom applications round off the product range.
