less, it is important to confirm the characteristics (operation with the power supply on and off) during design,

USAGE CAUTIONS
1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static
electricity when handling.
2. By-pass capacitor of 0.1 μF is used between VCC and GND near device. Also, ensure that the distance between
the leads of the photocoupler and capacitor is no more than 10 mm.
3. Avoid storage at a high temperature and high humidity.

• Time
10 seconds or less
• Preheating conditions
120°C or below (package surface temperature)

• Flux
Rosin flux containing small amount of chlorine (The flux with a maximum chlorine
content of 0.2 Wt% is recommended.)
(3) 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 side may enter the on state, even if the voltage is within the absolute
maximum ratings.
