NOTES ON HANDLING
1. Recommended soldering conditions
(1) Infrared reflow soldering
• Peak reflow temperature 260°C or below (package surface temperature)
• Time of peak reflow temperature 10 seconds or less
• Time of temperature higher than 220°C 60 seconds or less
• Time to preheat temperature from 120 to 180°C 120±30 s
• Number of reflows Three or less
• Flux Rosin flux containing small amount of chlorine (The flux with a maximum
chlorine content of 0.2 Wt% or less 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% or less is recommended.)
(3) Soldering by Soldering Iron
• Peak Temperature (lead part temperature) 350°C or below
• Time (each pin) 3 seconds or less
• Flux Rosin flux containing small amount of chlorine (The flux with a maximum
chlorine content of 0.2 Wt% or less is recommended.)
(a) Soldering of leads should be made at the point 1.5 to 2.0 mm from the root of the lead
(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 at startup, the output
transistor may enter the on state, even if the voltage is within the absolute maximum ratings.
