Device Degradation

Projected Operating Life Based on LED Light Output Degradation
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.
