ZVHT SMD Series - Low Voltage, High Temperature Varistors
General Information
Multilayered Varistor Symbol
The ZVHT series of low voltage multilayered varistors is designed to protect sensitive
electronic devices against high voltage surges in the low voltage region. They offer
excellent transient energy absorption due to improved energy volume distribution and
power dissipation. Low voltage varistors cover a wide DC operating voltage range
from 3 V to 170 V.
U
In addition, the ZVHT series exhibits independent suppression characteristics
enabling stable protection over a wide temperature range of -55 to +150 °C.
ZVHT series varistors are typically applied to protect integrated circuits and other
components at the circuit board level.

ZVHT SMD Series - Low Voltage, High Temperature Varistors
Soldering Recommendations for SMD Components
Popular soldering techniques used for surface mounted components are Wave and Infrared Reflow processes. Both processes can be
performed with Pb-containing or Pb-free solders. The terminations for these soldering techniques are NiSn Barrier Type End
Terminations.

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. SMD varistors
to be wave soldered are first glued to the circuit board, usually with an epoxy adhesive. When all components on the PCB have been
positioned and an appropriate amount of 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 Soldering
These reflow processes are typically associated with top-side component placement. This technique utilizes a mixture of adhesive and
solder compounds (and sometimes fluxes) that are blended into a paste. The paste is then screened onto PCB soldering pads specifi-
cally designed to accept a particular sized SMD component. The recommended solder paste wet layer thickness is 100 to 300 µm. Once
the circuit board is fully populated with SMD components, it is placed in a reflow environment, where the paste is heated to slightly above
its eutectic temperature. When the solder paste reflows, the SMD components are attached to the solder pads.
Solder Fluxes
Solder fluxes are generally applied to populated circuit boards to keep oxides from forming during the heating process and to facilitate
the flowing of the solder. Solder fluxes can be either a part of the solder paste compound or separate materials, usually fluids.
Recommended fluxes are:
•
•
non-activated (R) fluxes, whenever possible
mildly activated (RMA) fluxes of class L3CN
• class ORLO
Activated (RA), water soluble or strong acidic fluxes with a chlorine content > 0.2 wt. % are NOT RECOMMENDED. The use of such
fluxes could create high leakage current paths along the body of the varistor components.
When a flux is applied prior to wave soldering, it is important to completely dry any residual flux solvents prior to the soldering process.
Thermal Shock
To avoid the possibility of generating stresses in the varistor chip due to thermal shock, a preheat stage to within 100 °C of the peak sol-
dering process temperature is recommended. Additionally, SMD varistors should not be subjected to a temperature gradient greater than
4 °C/sec., with an ideal gradient being 2 °C/sec. Peak temperatures should be controlled. Wave and Reflow soldering conditions for SMD
varistors with Pb-containing solders are shown on the next page in Fig. 1 and 2 respectively, while Wave and Reflow soldering conditions
for SMD varistors with Pb-free solders are shown in Fig. 1 and 3.
Whenever several different types of SMD components are being soldered, each having a specific soldering profile, the soldering profile
with the least heat and the minimum amount of heating time is recommended. Once soldering has been completed, it is necessary to
minimize the possibility of thermal shock by allowing the hot PCB to cool to less than 50 °C before cleaning.
Specifications are subject to change without notice.
Users should verify actual device performance in their specific applications.

Soldering Recommendations for SMD Components (Continued)
Inspection Criteria
When Wave or Infrared Reflow processes are used, the inspection criteria to determine acceptable solder joints will depend on several
key variables, principally termination material process profiles.
Pb-containing Wave and IR Reflow Soldering
Typical “before” and “after” soldering results for NiSn Barrier Type End Terminations can be seen in Fig. 4. NiSn Barrier Type 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 meet or
exceed established industry standards for adhesion.

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.
Since barrier type terminations on Bourns® chips do not require the use of sometimes problematic nickel and tin-alloy electroplating
processes, these varistors are truly considered environmentally friendly.
Specifications are subject to change without notice.
Users should verify actual device performance in their specific applications.

Solder Test and Retained Samples
Reflow soldering test based on J-STD-020D.1 and soldering test by dipping based on IEC 60068- 2 for Pb-free solders are performed on
each production lot as shown in the following chart. Test results and accompanying samples are retained for a minimum of two (2) years.
The solderability of a specific lot can be checked at any time within this period, should a customer require this information.

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
• Do not exceed the following soldering iron specifications:
Output Power.......................................30 Watts Maximum
Temperature of Soldering Iron Tip.......280 °C Maximum
Soldering Time.....................................10 Seconds Maximum
Storage Conditions
SMD varistors should be used within 1 year of purchase to avoid possible soldering problems caused by oxidized terminals. The storage
environment should be controlled, with humidity less than 40 % and temperature between -25 and +45 °C. Varistor chips should always
be stored in their original packaged unit.
When varistor chips have been in storage for more than 1 year, and when there is evidence of solderability difficulties, Bourns can often
“refresh” the terminations to eliminate these problems.
Specifications are subject to change without notice.
Users should verify actual device performance in their specific applications.

Reliability - Lifetime
Pb-free Wave and IR Reflow Soldering
In general, reliability is the ability of a component to perform and maintain its functions in routine circumstances, as well as in hostile or
unexpected circumstances.
The Mean life of the ZV series 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, and an intuitive corollary is that the rate changes over time versus the expected life cycle of a system.

Legal Disclaimer Notice
This legal disclaimer applies to purchasers and users of Bourns® products manufactured by or on behalf of Bourns, Inc. and its
affiliates (collectively, “Bourns”).
Unless otherwise expressly indicated in writing, Bourns® products and data sheets relating thereto are subject to change
without notice. Users should check for and obtain the latest relevant information and verify that such information is current and
complete before placing orders for Bourns® products.
The characteristics and parameters of a Bourns® product set forth in its data sheet are based on laboratory conditions, and
statements regarding the suitability of products for certain types of applications are based on Bourns’ knowledge of typical
requirements in generic applications. The characteristics and parameters of a Bourns® product in a user application may vary
from the data sheet characteristics and parameters due to (i) the combination of the Bourns® product with other components
in the user’s application, or (ii) the environment of the user application itself. The characteristics and parameters of a Bourns®
product also can and do vary in different applications and actual performance may vary over time. Users should always verify
the actual performance of the Bourns® product in their specific devices and applications, and make their own independent
judgments regarding the amount of additional test margin to design into their device or application to compensate for
differences between laboratory and real world conditions.
Unless Bourns has explicitly designated an individual Bourns® product as meeting the requirements of a particular industry
standard (e.g., ISO/TS 16949) or a particular qualification (e.g., UL listed or recognized), Bourns is not responsible for any
failure of an individual Bourns® product to meet the requirements of such industry standard or particular qualification. Users of
Bourns® products are responsible for ensuring compliance with safety-related requirements and standards applicable to their
devices or applications.
Bourns® products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining ap-
plications, nor in any other applications where failure or malfunction may result in personal injury, death, or severe property or
environmental damage. Unless expressly and specifically approved in writing by two authorized Bourns representatives on a
case-by-case basis, use of any Bourns® products in such unauthorized applications might not be safe and thus is at the user’s
sole risk. Life-critical applications include devices identified by the U.S. Food and Drug Administration as Class III devices and
generally equivalent classifications outside of the United States.
Bourns expressly identifies those Bourns® standard products that are suitable for use in automotive applications on such
products’ data sheets in the section entitled “Applications.” Unless expressly and specifically approved in writing by two
authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard products in an automotive
application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. If Bourns
expressly identifies a sub-category of automotive application in the data sheet for its standard products (such as infotainment
or lighting), such identification means that Bourns has reviewed its standard product and has determined that if such Bourns®
standard product is considered for potential use in automotive applications, it should only be used in such sub-category of
automotive applications. Any reference to Bourns® standard product in the data sheet as compliant with the AEC-Q standard
or “automotive grade” does not by itself mean that Bourns has approved such product for use in an automotive application.
Bourns® standard products are not tested to comply with United States Federal Aviation Administration standards generally
or any other generally equivalent governmental organization standard applicable to products designed or manufactured for
use in aircraft or space applications. Bourns expressly identifies Bourns® standard products that are suitable for use in aircraft
or space applications on such products’ data sheets in the section entitled “Applications.” Unless expressly and specifically
approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard
product in an aircraft or space application might not be safe and thus is not recommended, authorized or intended and is at the
user’s sole risk.
The use and level of testing applicable to Bourns® custom products shall be negotiated on a case-by-case basis by Bourns and
the user for which such Bourns® custom products are specially designed. Absent a written agreement between Bourns and the
user regarding the use and level of such testing, the above provisions applicable to Bourns® standard products shall also apply
to such Bourns® custom products.
Users shall not sell, transfer, export or re-export any Bourns® products or technology for use in activities which involve the
design, development, production, use or stockpiling of nuclear, chemical or biological weapons or missiles, nor shall they use
Bourns® products or technology in any facility which engages in activities relating to such devices. The foregoing restrictions
apply to all uses and applications that violate national or international prohibitions, including embargos or international
regulations. Further, Bourns® products and Bourns technology and technical data may not under any circumstance be
exported or re-exported to countries subject to international sanctions or embargoes. Bourns® products may not, without prior
authorization from Bourns and/or the U.S. Government, be resold, transferred, or re-exported to any party not eligible
to receive U.S. commodities, software, and technical data.
To the maximum extent permitted by applicable law, Bourns disclaims (i) any and all liability for special, punitive, consequential,
incidental or indirect damages or lost revenues or lost profits, and (ii) any and all implied warranties, including implied warranties
of fitness for particular purpose, non-infringement and merchantability.
