Metal Oxide Varistor Curves

This document contains charts showing the transient voltage-current characteristics and pulse rating curves for 5mm metal oxide varistors. The charts show: 1) The relationship between voltage and current under transient conditions for different 5mm varistor models, with maximum leakage current and clamping voltage indicated. 2) Pulse rating curves for 5mm varistor models showing the maximum current that can pass for different pulse durations before failure occurs. 3) Similar charts for high surge 5mm varistor models showing improved pulse rating performance.
