Abstract

When The temperature of the joining of SCR rises major changes of characteristics are increase of leakage current, decrease of break-down voltage, and increase of turn off time. Because these changes promote the inferiority of SCR it(SCR) will get out of control and its life time will be shortened and finally it will be destroyed. In this paper, we will measure the changes of the characteristics in accordance with a rise in temperature. On the basis of the result we will find out the appropriate time to change SCR and we will use the result for the maintenance of SCR and increase of reliability of SCR.
