Cautions and warnings
GeneralSome parts of this publication contain statements about the suitability of our transient voltage
suppressor (TVS) for certain areas of application, including recommendations aboutincorporation/design-in of these products into customer applications. The statements are based on
our knowledge of typical requirements often made of our TVS devices in the particular areas. We
nevertheless expressly point out that such statements cannot be regarded as binding statements
about the suitability of our TVS components for a particular customer application. As a rule, TDKElectronics is either unfamiliar with individual customer applications or less familiar with them than thecustomers themselves. For these reasons, it is always incumbent on the customer to check anddecide whether the TVS devices with the properties described in the product specification are suitablefor use in a particular customer application.
 Do not use TDK Electronics TVS components for purposes not identified in our specifications,application notes and data books.
 Ensure the suitability of a TVS in particular by testing it for reliability during design-in. Always
evaluate a TVS component under worst-case conditions.
 Pay special attention to the reliability of TVS devices intended for use in safety-critical applications(e.g. medical equipment, automotive, spacecraft, nuclear power plant).
Design notes Always connect a TVS in parallel with the electronic circuit to be protected.
 Consider maximum rated power dissipation if a TVS has insufficient time to cool down between anumber of pulses occurring within a specified isolated time period. Ensure that electricalcharacteristics do not degrade.
 Consider derating at higher operating temperatures. Choose the highest voltage class compatible
with derating at higher temperatures.
 Surge currents beyond specified values will puncture a TVS. In extreme cases a TVS will burst.
 If steep surge current edges are to be expected, make sure your design is as low-inductance aspossible.
 In some cases the malfunctioning of TVS 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 asspecified. In applications requiring a very high level of operational safety and especially when themalfunction or failure of a passive electronic component could endanger human life or health (e.g.
in accident prevention, life-saving systems, or automotive battery line applications such as clamp30), ensure by suitable design of the application 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 amalfunction or failure.
 Specified values only apply to TVS components that have not been subject to prior electrical,
mechanical or thermal damage. The use of TVS devices in line-to-ground applications is therefore
not advisable, and it is only allowed together with safety countermeasures like thermal fuses.

SD0201SL-ULC101

Storage Only store TVS in their original packaging. Do not open the package before storage.
 Storage conditions in original packaging: temperature −25 to +45°C, relative humidity ≤75% annualaverage, maximum 95%, dew precipitation is inadmissible.
 Do not store TVS devices where they are exposed to heat or direct sunlight. Otherwise the packaging
material may be deformed or TVS may stick together, causing problems during mounting.
 Avoid contamination of the TVS surface during storage, handling and processing.
 Avoid storing TVS devices in harmful environments where they are exposed to corrosive gases forexample (SOx, Cl).
 Use TVS as soon as possible after opening factory seals such as polyvinyl-sealed packages.
 Solder TVS components after shipment from TDK Electronics within the time specified:– TVS with Ni/Au termination, 12 months
Handling Do not drop TVS components and allow them to be chipped.
 Do not touch TVS with your bare hands - gloves are recommended.
 Avoid contamination of the TVS surface during handling.
 Washing processes may damage the product due to the possible static or cyclic mechanical loads(e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts, whichmight lead to reduced reliability or lifetime.
Mounting When TVS devices are encapsulated with sealing material or overmolded with plastic material,
electrical characteristics might be degraded and the life time reduced.
 Make sure an electrode is not scratched before, during or after the mounting process.
 Make sure contacts and housings used for assembly with TVS components are clean before
mounting.
 The surface temperature of an operating TVS can be higher. Ensure that adjacent components areplaced at a sufficient distance from a TVS to allow proper cooling.
 Avoid contamination of the TVS surface during processing.
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 cracks.
 Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack.

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 forcertain areas of application. These statements are based on our knowledge of typicalrequirements 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 arule, we are either unfamiliar with individual customer applications or less familiar with them thanthe customers themselves. For these reasons, it is always ultimately incumbent on the customer tocheck and decide whether a product with the properties described in the product specification issuitable 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 stateof the art, even if they are operated as specified. In customer applications requiring a very highlevel of operational safety and especially in customer applications in which the malfunction or failureof 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 orredundancy) 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 thispublication 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.tdk-electronics.tdk.com/material). Should you have any moredetailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in thispublication may change from time to time. The same is true of the corresponding productspecifications. 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 theforegoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to our General Terms andConditions of Supply.
7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard.
The IATF certifications confirm our compliance with requirements regarding the quality
management system in the automotive industry. Referring to customer requirements and customer
specific requirements (“CSR”) TDK always has and will continue to have the policy of respecting
individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateralrequirements, we hereby like to emphasize that only requirements mutually agreed upon canand will be implemented in our Quality Management System. For clarification purposes we liketo point out that obligations from IATF 16949 shall only become legally binding if individually agreed
upon.
