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 in 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 produce cracks 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:
When soldering the products, please be sure to minimize the working time, within the following limits:
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.
During soldering or other operations, the interior frame temperature of the device should never exceed 105°C.
Recommended screw torque through the mounting tab is 0,588 to 0.785 N • m (6 to 8 kgf • cm)

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.
