AVHT Series - High Temperature Automotive Grade Varistors

General Information

Multilayered Varistor Symbol

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^®AVHT Series multilayered varistors are

transient suppressors with temperature independent suppression characteristics

enabling protection from -55 °C to 150 °C.

AVHT 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.
