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