Surface Mount Varistors
VP Series Plastic Encapsulated 85°C
Overview
Applications
KEMET's VP series of low and medium voltage plastic-
encapsulated varistors are designed to protect electronic
equipment against high voltage surges in the low and
medium voltage region. They offer direct surface mount
equivalents to leaded disc varistors of 5 and 7 mm sizes.
Theꢀthermoplasticꢀencapsulationꢀisꢀnon-flammableꢀ
according to the standard UL 94 V-0. Contacts are made of
tinned copper sheet.
Typical applications include medical instruments, integrated
circuits and transistors, mobile communication, white
goods, entertainment electronics, lighting ballast, as well
as protection of low and medium voltage boards, remote
control and electrical counters and applications that are
exposed to humidity.
These transient voltage suppressors cover an operating
voltage Vrms from 11 V to 300 V, featuring maximum surge
currents from 100 A to 1,200 A.

dependꢀonꢀseveralꢀkeyꢀvariables,ꢀprincipallyꢀterminationꢀmaterialꢀprocessꢀprofiles.
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:

ꢀ
Storage Conditions – SMD varistors should be used within 1 year of purchase to avoid possible soldering problems caused by oxidized
terminals.ꢀTheꢀstorageꢀenvironmentꢀshouldꢀbeꢀcontrolled,ꢀwithꢀhumidityꢀlessꢀthanꢀ40%ꢀandꢀtemperatureꢀbetweenꢀ-25ꢀandꢀ45ꢀ°C.ꢀVaristorꢀ
