What is Understanding Metal Oxide Varistors about?
The document provides an overview of varistors, which are semiconductor devices that protect electrical circuits from voltage surges. It discusses how varistors work by clamping voltage levels through a non-linear resistance characteristic. Unlike fuses or circuit breakers, varistors suppress over-voltage transients through voltage-dependent conduction. The most common type is the metal oxide varistor (MOV), made from zinc oxide and other materials, which can rapidly absorb short-term voltage spikes.
