Toshiba photocouplers use one of four types of LEDs and a projection of the operating life has been made for each LED. The table on
page 57 shows the types of LED used in photocouplers and the figures on pages 58 to 60 show projections of long-term light output
performance and operating life. Note that these operating life data are estimates extrapolated from long-term light output degradation
over a single wafer lot and are shown as reference only.
F50% (cumulative failure rate 50%) operating life: Time period until the projected long-term light output degradation curve of
F0.1% (cumulative failure rate 0.1%) operating life: Time period until the projected long-term light output degradation curve of
The relationship between LED light output degradation and optical coupling characteristics is shown below.
