OPERATING PRECAUTIONS
In the case that you use Sanken products or design your products by using Sanken 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.
Because reliability can be affected adversely by improper storage environments and handling methods, please
observe the following cautions.
Cautions for Storage
Ensure that storage conditions comply with the standard temperature (5 to 35°C) and the standard relative humidity
(around 40 to 75%); avoid storage locations that experience extreme changes in temperature or humidity.
Avoid locations where dust or harmful gases are present and avoid direct sunlight.
Reinspect for rust on leads and solderability of the products that have been stored for a long time.
Cautions for Testing and Handling
When tests are carried out during inspection testing and other standard test periods, protect the products from power
surges from the testing device, shorts between the product pins, and wrong connections. Ensure all test parameters are
within the ratings specified by Sanken for the products.
Remarks About Using Thermal Silicone Grease
When thermal silicone grease is used, it shall be applied evenly and thinly. If more silicone grease than required is
applied, it may produce excess stress.
The thermal silicone grease that has been stored for a long period of time may cause cracks of the greases, and it
cause low radiation performance. In addition, the old grease may cause cracks in the resin mold when screwing the
products to a heatsink.
Fully consider preventing foreign materials from entering into the thermal silicone grease. When foreign material
is immixed, radiation performance may be degraded or an insulation failure may occur due to a damaged insulating
plate.
The thermal silicone greases that are recommended for the resin molded semiconductor should be used.
Our recommended thermal silicone grease is the following, and equivalent of these.

Soldering
When soldering the products, please be sure to minimize the working time, within the following limits:
・Reflow Preheat ; 180 °C / 90 ± 30 s
Solder heating ; 250 °C / 10 ± 1s (260 °C peak, 2 times)
・Soldering iron ; 380 ± 10 °C / 3.5 ± 0.5s (1 time)
Electrostatic Discharge
When handling the products, the operator must be grounded. Grounded wrist straps worn should have at least 1MΩ
of resistance from the operator to ground to prevent shock hazard, and it should be placed near the operator.
Workbenches where the products are handled should be grounded and be provided with conductive table and floor
mats.
When using measuring equipment such as a curve tracer, the equipment should be grounded.
When soldering the products, the head of soldering irons or the solder bath must be grounded in order to prevent
leak voltages generated by them from being applied to the products.
The products should always be stored and transported in Sanken shipping containers or conductive containers, or
be wrapped in aluminum foil.

environment, and the information, including its accuracy, usefulness, and reliability, included in this document.
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.
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.
