• 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.), and whenever long life expectancy is required even in general purpose
electronic equipment or apparatus, 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 our semiconductor devices or design your products by using our semiconductor devices, 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
devices. 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
(T_J) 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.
