The IREDs are wired in series; the value specified for forward voltage and the bias specified for reverse leakage are twice the values. expected for a single JRED. 2. Radiation outside the sensitivity range of the device may be present during these measurements. Sufficient protection has been provided when the parameter being measured cannot be altered by further Irradiation shielding. ~ 3. Other ranges of light current can be specified; call Senisys for applications assistance. 4. Crosstalk is measured by blocking the radiation exiting one IRED and measuring the value of sensor current In the same channel; snsor. current in excess of Iceo (or Ip) is considered crosstalk.
