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°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.
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.
Remarks About Using Silicone Grease with a 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 excess stress.
Volatile-type silicone greases may crack after long periods of
time, resulting in reduced heat radiation effect. Silicone grease
with low consistency (hard grease) may cause cracks in the mold
resin when screwing the product to a heatsink.
Our recommended silicone greases for heat radiation purposes,
which will not cause any adverse effect on the product life, are
indicated below:

Suppliers
G746
Shin-Etsu Chemical Co., Ltd.
YG6260
Momentive Performance Materials Holding, Inc.
SC102
Dow Corning Toray Co., Ltd.
Soldering
When soldering the products, please be sure to minimize the
working time, within the following limits:
260±5°C 10 s
350±5°C
3 s (solder iron)
Soldering iron should be at a distance of at least 1.5 mm from the
body of the products
Electrostatic Discharge
When handling the products, the operator must be grounded.
Grounded wrist straps worn should have at least 1 MΩ 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 other 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.
