Remarks About Using Silicone Grease with a Heatsink
•
•
Operation of the product in parallel to increase current is not
permitted.
Although the product has an internal overtemperature protection
circuit, that is intended only to protect the product from temporary
excess heating due to overloads. Long-term reliability cannot
be guaranteed when the product is operated under continuous
overload conditions.
Ensure that storage conditions comply with the standard
temperature (5°C 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 products that have
been stored for a long time.
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 adjacent products, and
shorts to the heatsink.
When silicone grease is used in mounting this product on a
heatsink, it shall be applied evenly and thinly. If more silicone
grease than required is applied, it may produce stress.
Volatile-type silicone greases may permeate the product and
produce cracks after long periods of time, resulting in reduced
heat radiation effect, and possibly shortening the lifetime of the
product.
WARNING — These devices are designed to be operated at lethal voltages and energy levels. Circuit designs
that embody these components must conform with applicable safety requirements. Pre cau tions must be
taken to prevent accidental contact with power-line potentials. Do not connect ground ed test equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.

torque for this product package type is: 58.8 to 68.6 N•cm (6.0 to
7.0 kgf•cm).
Our recommended silicone greases for heat radiation purposes,
which will not cause any adverse effect on the product life, are
indicated below:
When soldering the products, please be sure to minimize the
working time, within the following limits:
260±5°C 10 s
350±5°C
Soldering iron should be at a distance of at least 1.5 mm from the
body of the products
When handling the products, operator must be grounded.
Grounded wrist straps worn should have at least 1 MΩ of
resistance to ground to prevent shock hazard.
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 other to prevent leak voltages
generated by them from being applied to the products.
The products should always be stored and transported in our
shipping containers or conductive containers, or be wrapped in
aluminum foil.
