(3) soldering by soldering iron peak temperature (l ead part temperature) 350 c or below time (each pins) 3 seconds or less flux rosin flux containing small amount of chlorine (the flux with a maximum chlorine content of 0.2 wt% is recommended.) (a) soldering of leads should be made at the poi nt 1.5 to 2.0 mm from the root of the lead (b) please be sure that the temperatur e of the package woul d not be heated over 100 c data sheet pn10399ej03v0ds 10 ps2805a-1,ps2805a-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 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 within 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 vari ations or the like. this tendency may sometimes be obvious, especially below i f = 1 ma. therefore, check the charac teristics under the actual operating conditi ons 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 te mperature and high humidity. data sheet pn10399ej03v0ds 11 ps2805a-1,ps2805a-4
