Test Test methods/ conditions Requirement
Varistor voltage The voltage between two terminals with
the specified measuring current applied
is called V
(1 mADC @ 0.2 … 2 s).
v
Clamping voltage The maximum voltage between two
terminals with the specified standard
impulse current (8/20 µs) applied.
Max. DC operating voltage The maximum allowable DC operating
voltage VDC at UCT +5/–0 °C is
applied for 1000 ±48 h.
The leakage current I

Block varistors
HighE series
Cautions and warnings
General
1. EPCOS metal oxide varistors (SIOVs) are designed for specific applications and should not be
used for purposes not identified in our specifications, application notes and data books unless
otherwise agreed with EPCOS during the design-in-phase.
2. Ensure suitability of SIOVs through reliability testing during the design-in phase. SIOVs should
be evaluated taking into consideration worst-case conditions.
3. For applications of SIOVs in line-to-ground circuits based on various international and local
standards there are restrictions existing or additional safety measures required.
Storage
1. Store SIOVs only in original packaging. Do not open the package before storage.
2. Storage conditions in original packaging:
Storage temperature: –25 °C … +45 °C
Relative humidity: <75% annual average,
<95% on maximum 30 days a year.
Dew precipitation: Is to be avoided.
3. Avoid contamination of an SIOV’s surface during storage, handling and processing.
4. Avoid storage of SIOVs in harmful environments that can affect the function during long-term
operation (examples given under operation precautions).
5. The SIOV type series should be soldered within the time specified:
SIOV-S, -Q, -LS 24 months
ETFV and SFS types 12 months.
Handling
1. SIOVs must not be dropped.
2. Components must not be touched with bare hands. Gloves are recommended.
3. Avoid contamination of the surface of SIOV electrodes during handling, be careful of the sharp
edge of SIOV electrodes.
Soldering (where applicable)
1. Use rosin-type flux or non-activated flux.
2. Insufficient preheating may cause ceramic cracks.
3. Rapid cooling by dipping in solvent is not recommended.
4. Complete removal of flux is recommended.

Important notes at the end of this document.

HighE series
Mounting
1. Potting, sealing or adhesive compounds can produce chemical reactions in the SIOV ceramic
that will degrade the component’s electrical characteristics.
2. Overloading SIOVs may result in ruptured packages and expulsion of hot materials. For this rea-
son SIOVs should be physically shielded from adjacent components.
Operation
1. Use SIOVs only within the specified temperature operating range.
2. Use SIOVs only within the specified voltage and current ranges.
3. Environmental conditions must not harm SIOVs. Use SIOVs only in normal atmospheric condi-
tions. Avoid use in the presence of deoxidizing gases (chlorine gas, hydrogen sulfide gas,
ammonia gas, sulfuric acid gas, etc), corrosive agents, humid or salty conditions. Avoid contact
with any liquids and solvents.

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical
requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application. As
a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them
than the customers themselves. For these reasons, it is always ultimately incumbent on the
customer to check and decide whether an EPCOS product with the properties described in the
product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of passive electronic components
or failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified. In customer applications
requiring a very high level of operational safety and especially in customer applications in which
the malfunction or failure of a passive electronic component could endanger human life or health
(e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of
suitable design of the customer application or other action taken by the customer (e.g.
installation of protective circuitry or redundancy) that no injury or damage is sustained by third
parties in the event of malfunction or failure of a passive electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our
Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more
detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order. We also
reserve the right to discontinue production and delivery of products. Consequently, we
cannot guarantee that all products named in this publication will always be available. The
aforementioned does not apply in the case of individual agreements deviating from the foregoing
for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version
of the “General Terms of Delivery for Products and Services in the Electrical Industry”
published by the German Electrical and Electronics Industry Association (ZVEI).
7. The trade names EPCOS, BAOKE, Alu-X, CeraDiode, CSSP, DSSP, MiniBlue, MKK, MLSC,
MotorCap, PCC, PhaseCap, PhaseMod, SIFERRIT, SIFI, SIKOREL, SilverCap, SIMDAD,
