NOTES ON HANDLING
1. Recommended soldering conditions
(1) Infrared reflow soldering
• Peak reflow temperature 260C or below (package surface temperature)
• 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 12030 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 260C or below (molten solder temperature)
• Time 10 seconds or less
• Preheating conditions 120C 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) 350C 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 100C.

(4) Cautions
• Fluxes
Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
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. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.
