data sheet pn10230ej0 4 v0ds 10 ps2521 - 1,ps2521l - 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 between the photocouplers input and output or between collecto r - 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 be fore 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. therefore, check the characteristics under the actual operating conditions and thorough ly 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.
