PS2502-1,-4,PS2502L-1,-4
(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 rati ngs.
3. Measurement conditions of current transfer ratios (CTR), which differ according to photocoupler
Check the setting v alues before use, since the forward current conditions at CT R measurement differ according
to prod uct.
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.

5. Renesas Electronics products are classied according to the following two quality grades: “Standard” and “High Quality”. The recommended applications
for each Renesas Electronics product depends on the product’s quality grade, as indicated below. “Standard”: Computers; ofce equipment; communications
equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic equipment; and
industrial robots etc. “High Quality”: Transportation equipment (automobiles, trains, ships, etc.); trafc control systems; anti-disaster systems; anti-crime
systems; and safety equipment etc. Renesas Electronics products are neither intended nor authorized for use in products or systems that may pose a direct
threat to human life or bodily injury (articial life support devices or systems, surgical implantations etc.), or may cause serious property damages (nuclear
reactor control systems, military equipment etc.). You must check the quality grade of each Renesas Electronics product before using it in a particular
application. You may not use any Renesas Electronics product for any application for which it is not intended. California Eastern Laboratories and Renesas
Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product
for which the product is not intended by California Eastern Laboratories or Renesas Electronics.
6. You should use the Renesas Electronics products described in this document within the range specied by California Eastern Laboratories, especially with
respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, installation and other product
characteristics. California Eastern Laboratories shall have no liability for malfunctions or damages arising out of the use of Renesas Electronics products
beyond such specied ranges.
7. Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have specic characteristics such as
the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further, Renesas Electronics products are not subject to radiation
