Abstract:
Transient voltage suppression (TVS) based on multilayer varistors (MLVs) is designed to prevent damage to sensitive devices and circuits from voltage spikes. The damage to sensors, circuits and electronic components can disable critical functions, rendering a vehicle inoperable until repairs are made. Sources of damaging voltage spikes can include electrostatic discharges (ESD, or static shock), induced secondary voltage from lightning strikes (a high voltage ESD), electromagnetic pulses, voltage surge from motor switching, jump starts, energizing solenoid coil actuators, arcing from faults and load dump from alternator switching. When an electrical circuit or system experiences damaging voltage spikes, a normally off MLV is activated and protects the device by redirecting the spike to ground.
