2 Soldering guidelines
The use of mild, non-activated fluxes for soldering is recommended, as well as proper cleaning of
the PCB.
The components are suitable for reflow soldering to JEDEC J-STD-020D.
3 Solder joint profiles / solder quantity
3.1 Cement quantity
The component is fixed onto the circuit board with cement prior to soldering. It must still be able
to move slightly. When the board is placed into the reflow oven, excessively rigid fixing can lead
to high forces acting on the component and thus to a break. In addition, too much cement can
lead to unsymmetrical stressing and thus to mechanical fracture of the component. The cement
must also be so soft during mounting that no mechanical stressing occurs.
3.2 Mounting the components on the board
It is best to mount the components on the board before soldering so that one termination does not
enter the oven first and the second termination is soldered subsequently. The ideal case is simul-
taneous wetting of both terminations.
3.3 Solder joint profiles
If the meniscus height is too low, that means the solder quantity is too low, the solder joint may
break, i.e. the component becomes detached from the joint. This problem is sometimes interpret-
ed as leaching of the external terminations.
If the solder meniscus is too high, i.e. the solder quantity is too large, the vise effect may occur.
As the solder cools down, the solder contracts in the direction of the component. If there is too
much solder on the component, it has no leeway to evade the stress and may break, as in a vise.

5 Notes for proper soldering
5.1 Preheating and cooling
The average ramp-up rate must not exceed 3 °C/s.
The cooling rate must not exceed 8 °C/s.
5.2 Repair / rework
Manual soldering with a soldering iron must be avoided, hot-air methods are recommended for
making repairs.
5.3 Cleaning
All environmentally compatible agents are suitable for cleaning. Select the appropriate cleaning
solution according to the type of flux used. The temperature difference between the components
and cleaning liquid must not be greater than 100 °C. Ultrasonic cleaning should be carried out
with the utmost caution. Too high ultrasonic power can impair the adhesive strength of the metal-
lized surfaces. Insufficient or excessive cleaning can be detrimental to CeraDiode performance.
5.4 Solder paste printing (reflow soldering)
An excessive application of solder paste results in too high a solder fillet, thus making the chip
more susceptible to mechanical and thermal stress. This will lead to the formation of cracks. Too
little solder paste reduces the adhesive strength on the outer electrodes and thus weakens the
bonding to the PCB. The solder should be applied smoothly to the end surface to a height of
min. 0.2 mm.
5.5 Selection of flux
Used flux should have less than or equal to 0.1 wt % of halogenated content, since flux residue
after soldering could lead to corrosion of the termination and/or increased leakage current on the
surface of the CeraDiode. Strong acidic flux must not be used. The amount of flux applied should
be carefully controlled, since an excess may generate flux gas, which in turn is detrimental to sol-
derability.
5.6 Storage
Solderability is guaranteed for one year from date of delivery, provided that components are
stored in their original packages.
Storage temperature: 25 °C to +45 °C
Relative humidity: ≤75% annual average, ≤95% on 30 days a year
The solderability of the external electrodes may deteriorate if SMDs are stored where they are ex-
posed to high humidity, dust or harmful gas (hydrogen chloride, sulfurous acid gas or hydrogen
sulfide).
Do not store SMDs where they are exposed to heat or direct sunlight. Otherwise the packing ma-
terial may be deformed or SMDs may stick together, causing problems during mounting.
After opening the factory seals, such as polyvinyl-sealed packages, it is recommended to use the
SMDs as soon as possible.

Standard series
Page 16 of 22Please read Cautions and warnings and
Important notes at the end of this document.
5.7 Placement of components on circuit board
It is of advantage to place the components on the board before soldering so that their two termi-
nals do not enter the solder oven at different times. Ideally, both terminals should be wetted si-
multaneously.
5.8 Soldering caution
Sudden heating or cooling of the component results in thermal destruction by cracks.
An excessively long soldering time or high soldering temperature results in leaching of the out-
er electrodes, causing poor adhesion due to loss of contact between electrodes and termina-
tion.
Avoid manual soldering with a soldering iron.
Wave soldering must not be applied for CeraDiodes designated for reflow soldering only.
Keep to the recommended down-cooling rate.

Cautions and warnings
General
Some parts of this publication contain statements about the suitability of our CeraDiodes for cer-
tain areas of application, including recommendations about incorporation/design-in of these prod-
ucts into customer applications. The statements are based on our knowledge of typical require-
ments often made of our CeraDiodes in the particular areas. We nevertheless expressly point out
that such statements cannot be regarded as binding statements about the suitability of our
CeraDiodes for a particular customer application. As a rule, EPCOS is either unfamiliar with indi-
vidual customer applications or less familiar with them than the customers themselves. For these
reasons, it is always incumbent on the customer to check and decide whether the CeraDiodes
with the properties described in the product specification are suitable for use in a particular cus-
tomer application.
Do not use EPCOS CeraDiodes for purposes not identified in our specifications, application
notes and data books.
Ensure the suitability of a CeraDiode in particular by testing it for reliability during design-in. Al-
ways evaluate a CeraDiode under worst-case conditions.
Pay special attention to the reliability of CeraDiodes intended for use in safety-critical applica-
tions (e.g. medical equipment, automotive, spacecraft, nuclear power plant).
Design notes
Always connect a CeraDiode in parallel with the electronic circuit to be protected.
Consider maximum rated power dissipation if a CeraDiode has insufficient time to cool down
between a number of pulses occurring within a specified isolated time period. Ensure that elec-
trical characteristics do not degrade.
Consider derating at higher operating temperatures. Choose the highest voltage class compati-
ble with derating at higher temperatures.
Surge currents beyond specified values will puncture a CeraDiode. In extreme cases a
CeraDiode will burst.
If steep surge current edges are to be expected, make sure your design is as low-inductance
as possible.
In some cases the malfunctioning of passive electronic components or failure before the end of
their service life cannot be completely ruled out in the current state of the art, even if they are
operated as specified. Do not use CeraDiodes in applications requiring a very high level of op-
erational safety and especially when the malfunction or failure of a passive electronic compo-
nent could endanger human life or health (e.g. in accident prevention, life-saving systems, or
automotive battery line applications such as clamp 30), ensure by suitable design of the appli-
cation or other measures (e.g. installation of protective circuitry or redundancy) that no injury or
damage is sustained by third parties in the event of such a malfunction or failure.
Specified values only apply to CeraDiodes that have not been subject to prior electrical, me-
chanical or thermal damage. The use of CeraDiodes in line-to-ground applications is therefore
not advisable, and it is only allowed together with safety countermeasures like thermal fuses.
CeraDiodes
Standard series
Page 19 of 22Please read Cautions and warnings and
Important notes at the end of this document.
Storage
Only store CeraDiodes in their original packaging. Do not open the package before storage.
Storage conditions in original packaging: temperature -25 to +45°C, relative humidity ≤75% an-
nual average, maximum 95%, dew precipitation is inadmissible.
Do not store CeraDiodes where they are exposed to heat or direct sunlight. Otherwise the
packaging material may be deformed or CeraDiodes may stick together, causing problems dur-
ing mounting.
Avoid contamination of the CeraDiode surface during storage, handling and processing.
Avoid storing CeraDiodes in harmful environments where they are exposed to corrosive gases
for example (SOx, Cl).
Use CeraDiodes as soon as possible after opening factory seals such as polyvinyl-sealed pack-
ages.
Solder CeraDiodes after shipment from EPCOS within the time specified: 12 months.
Handling
Do not drop CeraDiodes and allow them to be chipped.
Do not touch CeraDiodes with your bare hands - gloves are recommended.
Avoid contamination of the CeraDiode surface during handling.
Mounting
When CeraDiodes are encapsulated with sealing material or overmolded with plastic material,
be aware that potting, sealing or adhesive compounds can produce chemical reactions in the
CeraDiode ceramic that will degrade its electrical characteristics and reduce its lifetime.
Make sure an electrode is not scratched before, during or after the mounting process.
Make sure contacts and housings used for assembly with CeraDiodes are clean before mount-
ing.
The surface temperature of an operating CeraDiode can be higher. Ensure that adjacent com-
ponents are placed at a sufficient distance from a CeraDiode to allow proper cooling.
Avoid contamination of the CeraDiode surface during processing.
Only CeraDiodes with an Ni barrier termination are approved for lead-free soldering.
Soldering
Complete removal of flux is recommended to avoid surface contamination that can result in an
instable and/or high leakage current.
Use resin-type or non-activated flux.
Bear in mind that insufficient preheating may cause ceramic cracks.
Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack.

Operation
Use CeraDiodes only within the specified operating temperature range.
Use CeraDiodes only within specified voltage and current ranges.
Environmental conditions must not harm a CeraDiode. Only use them in normal atmospheric
conditions. Reducing the atmosphere (e.g. hydrogen or nitrogen atmosphere) is prohibited.
Prevent a CeraDiode from contacting liquids and solvents. Make sure that no water enters a
CeraDiode (e.g. through plug terminals).
Avoid dewing and condensation.

Important notes at the end of this document.
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 re-
quirements 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 incum-
bent on the customer to check and decide whether an EPCOS product with the properties de-
scribed 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 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 an electronic component could endanger human life or
health (e.g. in accident prevention or lifesaving 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 an 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 Ma-
terial Data Sheets on the Internet (www.epcos.com/material). Should you have any more de-
tailed 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 fore-
going for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current ver-
sion of the "General Terms of Delivery for Products and Services in the Electrical In-
dustry" published by the German Electrical and Electronics Industry Association
(ZVEI).
