Surface Mount Varistors
VC Series Low Voltage 125°C
Overview
Applications
KEMET's VC series of low voltage varistors are designed
to protect sensitive electronic devices against high voltage
surges in the low voltage region. VC varistors offer excellent
transient energy absorption due to improved energy volume
distribution and power dissipation.
Typical applications include mobile phones and
telecommunication infrastructure, I/O ports and controllers.
The protection of integrated circuits and other components
at the circuit board level including the suppression of
inductive switching or other transient events such as surge
voltage. ESD protection for components sensitive to IEC
1000–4–2, MILSTD 883C Method 3015.7 and other industry
specifications.ꢀReplacementꢀofꢀlargerꢀsurfaceꢀmountꢀ
TVS Zeners in many applications. Designed to achieve
electromagnetic compliance of end products and provide
on-board transient voltage protection of ICs and transistors.

Reliability
In general, reliability is the ability of a component to perform and maintain its functions in routine circumstances, as well as
hostile or unexpected circumstances. The mean life of series components is a function of:
• Factor of Applied Voltage
• Ambient temperature
Mean life is closely related to Failure rate (formula).
Mean life (ML) is the arithmetic mean (average) time to failure of a component.
Failure rate is the frequency with which an engineered system or component fails, expressed for example in failures per
hour. Failure rate is usually time dependent, an intuitive corollary is that the rate changes over time versus the expected
life cycle of a system.

Wave Soldering – this process is generally associated with discrete components mounted on the underside of printed circuit boards, or
for large top-side components with bottom-side mounting tabs to be attached, such as the frames of transformers, relays, connectors,
etc.ꢀSMDꢀvaristorsꢀtoꢀbeꢀwaveꢀsolderedꢀareꢀfirstꢀgluedꢀtoꢀtheꢀcircuitꢀboard,ꢀusuallyꢀwithꢀanꢀepoxyꢀadhesive.ꢀWhenꢀallꢀcomponentsꢀonꢀtheꢀ
PCB have been positioned and an appropriate time is allowed for adhesive curing, the completed assembly is then placed on a conveyor
and run through a single, double wave process.
Infrared Reflow Solderingꢀ–ꢀtheseꢀreflowꢀprocessesꢀareꢀtypicallyꢀassociatedꢀwithꢀtop-sideꢀcomponentꢀplacement.ꢀThisꢀtechniqueꢀutilizesꢀ
aꢀmixtureꢀofꢀadhesiveꢀandꢀsolderꢀcompoundsꢀ(andꢀsometimesꢀfluxes)ꢀthatꢀareꢀblendedꢀintoꢀaꢀpaste.ꢀTheꢀpasteꢀisꢀthenꢀscreenedꢀontoꢀPCBꢀ
solderingꢀpadsꢀspecificallyꢀdesignedꢀtoꢀacceptꢀaꢀparticularꢀsizedꢀSMDꢀcomponent.ꢀTheꢀrecommendedꢀsolderꢀpasteꢀwetꢀlayerꢀthicknessꢀ
isꢀ100ꢀtoꢀ300ꢀµm.ꢀOnceꢀtheꢀcircuitꢀboardꢀisꢀfullyꢀpopulatedꢀwithꢀMDꢀcomponents,ꢀitꢀisꢀplacedꢀinꢀaꢀreflowꢀenvironment,ꢀwhereꢀtheꢀpasteꢀisꢀ
heatedꢀtoꢀslightlyꢀaboveꢀitsꢀeutecticꢀtemperature.ꢀWhenꢀtheꢀsolderꢀpasteꢀreflows,ꢀtheꢀSMDꢀcomponentsꢀareꢀattachedꢀtoꢀtheꢀsolderꢀpads.
Solder Fluxesꢀ–ꢀsolderꢀfluxesꢀareꢀgenerallyꢀappliedꢀtoꢀpopulatedꢀcircuitꢀboardsꢀtoꢀcleanꢀoxidesꢀformingꢀduringꢀtheꢀheatingꢀprocessꢀandꢀtoꢀ

fluids.ꢀRecommendedꢀfluxesꢀare:
ꢀ
ꢀ
•ꢀnon-activatedꢀ(R)ꢀfluxes,ꢀwheneverꢀpossibleꢀ
•ꢀmildlyꢀactivatedꢀ(RMA)ꢀfluxesꢀofꢀclassꢀL3CN

Activated (RA),ꢀwaterꢀsolubleꢀorꢀstrongꢀacidicꢀfluxesꢀwithꢀaꢀchlorineꢀcontentꢀ>ꢀ0.2ꢀwt.ꢀ%ꢀareꢀNOTꢀRECOMMENDED.ꢀTheꢀuseꢀofꢀsuchꢀfluxesꢀ
could create high leakage current paths along the body of the varistor components.
Whenꢀaꢀfluxꢀisꢀappliedꢀpriorꢀtoꢀwaveꢀsoldering,ꢀitꢀisꢀimportantꢀtoꢀcompletelyꢀdryꢀanyꢀresidualꢀfluxꢀsolventsꢀpriorꢀtoꢀtheꢀsolderingꢀprocess.
Thermal Shock – to avoid the possibility of generating stresses in the varistor chip due to thermal shock, a preheat stage to within 100
°Cꢀofꢀtheꢀpeakꢀsolderingꢀprocessꢀtemperatureꢀisꢀrecommended.ꢀAdditionally,ꢀSMDꢀvaristorsꢀshouldꢀnotꢀbeꢀsubjectedꢀtoꢀaꢀtemperatureꢀ

Pb-contining Wave and IR Reflow Soldering – typical “before” and “after” soldering results for Barrier Type End Terminations can be seen
in Fig. 4. Barrier type terminated varistors form a reliable electrical contact and metallurgical bond between the end terminations and the
solder pads. The bond between these two metallic surfaces is exceptionally strong and has been tested by both vertical pull and lateral
(horizontal) push tests. The results exceed established industry standards for adhesion.
The solder joint appearance of a barrier type terminated varistor shows that solder forms a metallurgical junction with the thin tin-alloy
(over the barrier layer), and due to its small volume “climbs” the outer surface of the terminations, the meniscus will be slightly lower.
This optical appearance should be taken into consideration when programming visual inspection of the PCB after soldering.

Pb-free Wave and IR Reflow Soldering – typical “before” and “after” soldering results for Barrier Type End Terminations are given
in a phenomenon knows as “mirror” or “negative” meniscus. Solder forms a metallurgical junction with the entire volume of the end
termination, i.e. it diffuses from pad to end termination across the inner side, forming a “mirror” or “negative” meniscus. The height of the
solder penetration can be clearly seen on the end termination and is always 30% higher than the chip height.

Rework Criteria Soldering Iron – unless absolutely necessary, the use of soldering irons is NOT recommended for reworking varistor
chips. If no other means of rework is available, the following criteria must be strictly followed:
• Do not allow the tip of the iron to directly contact the top of the chip
•ꢀDoꢀnotꢀexceedꢀtheꢀfollowingꢀsolderingꢀironꢀspecifications:
Output Power:
TemperatureꢀofꢀSolderingꢀIronꢀTip:ꢀꢀ
Soldering Time:
30 Watts maximum
280°Cꢀmaximum
10 Seconds maximum
ꢀ
Storage Conditions – SMD varistors should be used within 1 year of purchase to avoid possible soldering problems caused by oxidized

Load Dump is a transient which occurs in an automotive environment. It is an exponentially
decaying positive voltage which occurs in the event of a battery disconect while the alternator
is still generating charging current with other loads remaining on the alternator circuit at the
time of battery disconect
