Many electronic systems in vehicles make driving safer and more comfortable. Almost all electronic systems in an automobile, e.g., anti-lock brake system, direct ignition system, airbag control system, wiper motors, etc. are susceptible to damage from destructive voltage transients. Bourns® AV Series multilayered varistors are transient suppressors with temperature independent suppression characteristics enabling protection from -55 to +125 °C. AV Series varistors offer excellent transient energy distribution. AV varistors require significantly less space and pad area than silicon TVS diodes, offering greater circuit board layout flexibility for the designer. Compared to common disc varistors, automotive varistors and varistor + capacitor EMI filters offer better electrical performance in much smaller case sizes.
