IMPORTANTS NOTES
 The contents in this document are subject to changes, for improvement and other purposes, without notice.
Make sure that this is the latest revision of the document before use.
 Application and operation examples described in this document are quoted for the sole purpose of reference for
the use of the products herein and Sanken can assume no responsibility for any infringement of industrial
property rights, intellectual property rights or any other rights of Sanken or any third party which may result
from its use.
 Although Sanken undertakes to enhance the quality and reliability of its products, the occurrence of failure and
defect of semiconductor products at a certain rate is inevitable. Users of Sanken products are requested to take,
at their own risk, preventative measures including safety design of the equipment or systems against any
possible injury, death, fires or damages to the society due to device failure or malfunction.
 Sanken products listed in this document are designed and intended for the use as components in general purpose
electronic equipment or apparatus (home appliances, office equipment, telecommunication equipment,
measuring equipment, etc.).
When considering the use of Sanken products in the applications where higher reliability is required
(transportation equipment and its control systems, traffic signal control systems or equipment, fire/crime alarm
systems, various safety devices, etc.), please contact your nearest Sanken sales representative to discuss, prior to
the use of the products herein.
The use of Sanken products without the written consent of Sanken in the applications where extremely high
reliability is required (aerospace equipment, nuclear power control systems, life support systems, etc.) is strictly
prohibited.
 In the case that you use Sanken semiconductor products or design your products by using Sanken
semiconductor products, the reliability largely depends on the degree of derating to be made to the rated values.
Derating may be interpreted as a case that an operation range is set by derating the load from each rated value or
surge voltage or noise is considered for derating in order to assure or improve the reliability. In general, derating
factors include electric stresses such as electric voltage, electric current, electric power etc., environmental
stresses such as ambient temperature, humidity etc. and thermal stress caused due to self-heating of
semiconductor products. For these stresses, instantaneous values, maximum values and minimum values must
be taken into consideration.
In addition, it should be noted that since power devices or IC’s including power devices have large self-heating
value, the degree of derating of junction temperature affects the reliability significantly.
 When using the products specified herein by either (i) combining other products or materials therewith or (ii)
physically, chemically or otherwise processing or treating the products, please duly consider all possible risks
that may result from all such uses in advance and proceed therewith at your own responsibility.
 Anti radioactive ray design is not considered for the products listed herein.
 Sanken assumes no responsibility for any troubles, such as dropping products caused during transportation out
of Sanken’s distribution network.
 The contents in this document must not be transcribed or copied without Sanken’s written consent.
