R08DS0202EJ0100 Rev.1.00 Dec 25, 2020 Page 10 of 12 PS2501-1, -4, PS2501L-1, -4 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 ratings. 3. Measurement conditions of current transfer ratios (CTR), which differ according to photocoupler Check the setting values before use, since the forward current conditions at CTR measurement differ according to product. 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. This tendency may sometimes be obvious, especially below IF = 1 mA. Therefore, check the characteristics under the actual operating conditions and thoroughly take variations or the like into consideration before use. USAGE CAUTIONS 1. 2. 3. 4. Protect against static electricity when handling. Avoid storage at a high temperature and high humidity. Avoid cleaning with Freon based or halogen-based (chlorinated etc.) solvents. Do not use fixing agents or coatings containing halogen-based substances.
