Keko attained UL-CSA approval

UL-CSA File E221545 covers ZV voltage range from 2 to 95 Vac (3 to 125 Vdc) and chip sizes from 0603 to 2220. ZV Series Varicons® are designed for use in the protection of low voltage board level products and components in the field of alarm systems, sensors, control and automation techniques, etc. Typical applications are : • Suppression of inductive switching or other transient events such as surge voltage at the circuit board level • ESD protection for components sensitive to IEC 1000-4-2, MIL-STD 883C Method 3015.7 and other industry specs. • ZVs can effectively replace larger surface mount TVS Zeners in many applications • ZVs can help achieve electromagnetic compliance of end products • ZVs provide on-board transient voltage protection of ICs and transistors
