Precautions for Photocouplers

1 For cleaning

I

( 1) Solvent cleaning : Solvent temperature 45°C or less

Immersion for 3 mm or less

(2) Ultrasonic

cleaning

: The effect to device by ultrasonic cleaning differs

by cleaning bath size, ultrasonic power

output, cleaning time, PCB size or device mounting

condition etc. Please test it in actual using condition

and confirm that doesn’t occur any defect before starting

the ultrasonic cleaning.

(31 Applicable solvent : Ethyl alcohol, Methyl alcohol, Isopropyl alcohol

In case when the other solvent is used, there are cases that

the packaging resin is eroded. Please use the other solvent

after thorough confirmation is performed in actual using condition.

2. The LED used in the Photocoupler generally decreases the light emission power

by operation. In case of long operation time, please design the circuit with considering

the degradation of the light emission power of the LED. (50%/5years)

3. There are cases that the deviation of the CTR and the degradation

of the LED become big at IF is less than 1 .OmA.

Please design the circuit with considering this point.
