PFC/DC-DC Systematic Combo Power IC
STR-E1555
Cautions for Storage
• Ensure that storage conditions comply with the standard temperature (5 to 35
• Avoid locations where dust or harmful gases are present and avoid direct sunlight.
• Reinspect for rust in leads and solderability that have been stored for a long time.
Cautions for characteristic Tests and Handling
When characteristic tests are carried out during inspection testing and other standard tests periods, protect the devices
from surge of power from the testing device, shorts between the devices and the heatsink.
Remarks in using silicone grease for 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 forced stress.
Volatile type silicone grease may produce cracks after elapse of long term, resulting in reducing heat radiation effect.
Silicone grease with low consistency (hard grease) may cause cracks in the mold resin when screwing the product to a
heatsink.

Considerations to protect the Products from Electrostatic Discharge
• When handling the devices, operator must be grounded. Grounded wrist straps be worn and should have at least
• Workbenches where the devices are handled should be grounded and be provided with conductive table and floor
• When using measuring equipment such as a curve tracer, the equipment should also be grounded.
• When soldering the devices, the head of a soldering iron or a solder bath must be grounded in other to prevent leak
• The devices should always be stored and transported in our shipping containers or conductive containers, or be
