Title: The accelerated life experiment study of Solid State Relay
Abstract: The operational principle of SSR (Solid State Relay) has been analyzed, and the methods of acceleration life experiments of SSR has been designed. The acceleration life experiment has been conducted under the condition of 125 degree centigrade junction temperature. According to the 0 number device failure in the acceleration life experiment, using unilateral approximate, the lower limit value of MTBF has been calculated under the condition of 90 percent confidence level. If the typical value of 0.7eV active energy for the SSR degradation is choosed in the accelerated life experiment, then the lower limit value of MTBF can be calculated under the condition of 85 degree centigrade junction temperature.
