OPERATING PRECAUTIONS

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 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 products, shorts between the product pins, and wrong connections. In addition, avoid tests

exceeded ratings

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 grease for heat radiation purposes, which will not cause any adverse effect on the product life,

are indicated below:

Soldering

 When soldering the products, please be sure to minimize the working time, within the following limits.

・260±5°C

10±1 s(Flow, 2times)

・380±10°C

3.5±0.5s (Soldering iron, 1time)

Soldering 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 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 a 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.
