Gamma Total Dose Radiation Performance of Skyworks Optocouplers
●Steady state total dose irradiation test, MIL-STD-883C, Method 019.2, was performed on various Isolink optocouplers and LED emitters to evaluate the effects of ionizing gamma radiation on their electrical and optical parameters. The results of the test overall showed excellent performance to 300K rads(Si) gamma total dose.
●The current transfer ratio is defined as the ratio of current generated at the output of the optocoupler divided by the input LED current. For the OLH500 logic gate optocoupler, the change in threshold current is plotted. (Figure 4) The threshold current is defined as the input LED current needed to cause a change of logic state in the output of the optocoupler.
