• Time of peak reflow temperature 10 seconds or less
• Time of temperature higher than 220C 60 seconds or less
• Time to preheat temperature from 120 to 180C 120 30 s
• Number of reflows Three
• Flux Rosin flux containing small amount of chlorine
(The flux with a maximum chlorine content of
0.2 Wt% is recommended.)
(2) Wave soldering
• Temperature 260 C or below (molten solder temperature)
• Time 10 seconds or less
• Preheating conditions 120 C or below (package surface temperature)
• Number of times One (Allowed to be dipped in solder including plastic mold portion.)
• Flux Rosin flux containing small amount of chlorine (The flux with a maximum
chlorine content of 0.2 Wt% is recommended.)
(3) Soldering by Soldering Iron
• Peak Temperature (lead part temperature) 350 C or below
• Time (each pins) 3 seconds or less
• Flux Rosin flux containing small amount of chlorine
(The flux with a maximum chlorine content of 0.2 Wt% is recommended.)
(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 100 C
(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.

Dec 25, 2020
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. This tendency may sometimes be
obvious, especially below IF = 1 mA.
Therefore, check the characteristics under the actual operating conditions and thoroughly take variations
or the like into consideration before use.
USAGE CAUTIONS
1. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.
3. Avoid cleaning with Freon based or halogen-based (chlorinated etc.) solvents.
4. Do not use fixing agents or coatings containing halogen-based substances.
