(a) Soldering of leads should be made at the point 1.5 to 2.0 mm from the root of the lead
(b) Please be sure that the temperature of the package would not be heated over 100C
(4) Cautions
• Flux Cleaning
Avoid cleaning with Freon based or halogen-based (chlorinated etc.) solvents.
• Do not use fixing agents or coatings containing halogen-based substances.

PS2706-1
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between
collector-emitters at startup, the output transistor may enter the on state, even if the voltage is within the
absolute maximum ratings.
3. Measurement conditions of current transfer ratios (CTR), which differ according to photocoupler
Check the setting values before use, since the forward current conditions at CTR measurement differ
according to product.
When using products other than at the specified forward current, the characteristics curves may differ
from the standard curves due to CTR value variations or the like. Therefore, check the characteristics
under the actual operating conditions and thoroughly take variations or the like into consideration before
use.
USAGE CAUTIONS
1.
2.
3.
4.
Protect against static electricity when handling.
Avoid storage at a high temperature and high humidity.
Avoid cleaning with Freon based or halogen-based (chlorinated etc.) solvents.
Do not use fixing agents or coatings containing halogen-based substances.
