我所1980年定型的WC52砷化镓双栅场效应晶体管于去年十二月中旬通过了四机部电子基础产品研究院颁布的考核规范(草案)C级标准后,紧接着将投入工作寿命考核的79只器件,在维持其考核条件(V_(ds)=3伏,I_(ds)=15毫安)下,不停顿地进行长期工作寿命试验.并已在250、500、1000、3120、6120小时对器件进行了五次测试,没有一只失效,总器件小时数已达483,480.第五次测试时间为1981年7月17日,目前试验还在继续进行.
Our 1980 stereotyped WC52 GaAs double-gate field-effect transistor passed the C-level standard of assessment (draft) promulgated by the Institute of Electronics Basic Products of the four-machine department in mid-December of last year and will be put into the work life assessment 79 devices were tested for long term service life without interruption while maintaining their test condition (V ds = 3 V, I ds ds = 15 mA) and have been tested at 250, 500, 1000, 3120, 6120 hours of the device has been tested five times, none of the failure, the total number of hours of the device has reached 483,480. The fifth test was July 17, 1981, the current test is continuing.
