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. Precautions must be

taken to prevent accidental contact with power-line potentials. Do not connect grounded test equipment.

The use of an isolation transformer is recommended during circuit development and breadboarding.

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 product that has

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 product from power surges from

the testing device, shorts between adjacent product packages,

and shorts to the heatsink.

•

The screwing torque for attaching a heatsink shall be 58.8 to

78.4 N•cm (6.0 to 8.0 Kgf•cm).

•

Ensure there are no foreign objects between the heatsink and thermal

pad; only silicone thermal grease is allowed.

Remarks About Using Silicone Grease with a Heatsink

•

When silicone grease is used in mounting this product with

a heatsink, grease 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.

•

Hard silicone greases may cause cracks in the product 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:

Soldering

•

When soldering the product, please be sure to minimize the

working time, within the following limits:

260±5°C 10 s

380±5°C

5 s

•

Soldering iron should be at a distance of at least 1.5 mm from the

body of the product

Electrostatic Discharge

•

When handling the product, 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 product is 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 product, 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 product.

•

The product should always be stored and transported in our

shipping containers or conductive containers, or be wrapped in

aluminum foil.
