Surface Mount Varistors
VA Automotive Grade 125°C
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 significantly less space and pad area than silicon
TVS diodes, offering greater circuit board layout flexibility
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.
Benefits
• AEC-Q200 qualified Grade 1
• Surface mount form factor
• Operating ambient temperature of −55°C to +125°C
• Supply voltage 12, 24, and 42 V
• Operating voltage range of 16 to 56 VDC
• Available case sizes: 0805, 1206, 1210, 1812, 2220
• Near zero inductance for the fastest speed of response to
transient surges
• Broad range of current and energy handling capabilities
• Low clamping voltage – Uc
• Non-plastic coating guarantees improved flammability
rating
• Non-sensitive to mildly activated fluxes
• Barrier type end terminations solderable with Pb-free
solders according to JEDEC J–STD–020C and IEC
60068–2–58
• RoHS 2 2011/65/EC, REACH compliant
