Surface Mount Varistors VA Automotive Grade 125C Overview Applications KEMET s VA series of varistors are transient suppressors Typical applications include almost all-electronic systems with temperature independent suppression characteristics in an automobile, anti-lock brake system, direct ignition enabling protection from 55C to +125C. system, airbag control system, wiper motors, and air conditioning systems that are susceptible to damage from VA varistors offer excellent transient energy distribution and destructive voltage transients. require significantly less space and pad area than silicon T VS diodes, offering greater circuit board layout flexibility for the designer.
