data sheet pn10061ej02v0ds 10 ps2911-1 (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 bet ween the photocoupler?s i nput and output or between collector-emitters at startup, the output transistor may enter the on state, even if the voltage is wi thin the absolute maximum ratings. 3. measurement conditions of current transfer ra tios (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 char acteristics curves may differ from the standard curves due to ctr value variati ons or the like. theref ore, check the characte ristics under the actual operating conditions and thoroughly take variations or the like into cons ideration before use. usage cautions 1. protect against static electricity when handling. 2. avoid storage at a high te mperature and high humidity.
