Notes
● Circuit design
(1) The LED used in the Phototriac coupler generally decreases the light emission power by operation.
In case of long operation time, please decide I
F
value as 2 times or more of the Maximum value
of the Minimum triggering current at circuit design with considering the decreases of the light
emission power of the LED. (50%/5years)
(2) Input current (I
F
) at off-state shall be set 0.1mA or less.
(3) In case that pulse drive is carried out, the pulse width of input signal should be 1ms or more.
● Usage
Only for triggering medium power triac and high power triac.
(This model shall be used under the condition on which power triac turns on.)
● Cleaning
(1) Solvent cleaning : Solvent temperature 45°C or less, Immersion for 3 min 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.
(3) Applicable solvents are as follows.
Applicable solvent : Ethyl alcohol, Methyl alcohol, Isopropyl alcohol
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.
● Precautions for Soldering Phototriac couplers
(1) In the case of flow soldering (Whole dipping is possible.)
It is recommended that flow soldering be carried out at 260°C or less
and within 10s (Pre-heating : 100 to 150°C, 30 to 80s).
(2 times or less)
(2) It is recommended to be done at the temperature and the time within the temperature profile as shown
in the figure below. (2 times or less)
(3) In the case of hand soldering
It is recommended that hand soldering be carried out at 400°C or less and within 3s : Within 2 times
(4) Other precautions
Depending on equipment and soldering conditions (temperature, Using solder etc.),
the effect to junction between PCB and lead pins of photocoupler is different.
Please confirm that there is no problem on the actual use conditions.
Pre-heat
150°C to 180°C, 120s or less
