MSK5971KRH and MSK5971KRHL RAD Hard Positive Voltage Regulator Total Dose Radiation Test Report

PublishTime：2022-11-10

●Introduction
■The total dose radiation test plan for the MSK5971KRH series was developed to qualify the devices as RAD Hard to 100 KRADS(Si). The testing was performed beyond 100 KRADS(Si) to show trends in device performance as a function of total dose. The test does not classify maximum radiation tolerance of the device, but simply offers designers insight to the critical parameter-shifts up to the specified total dose level. The MSK5971KRH and the MSK5971KRHL use the same active component. The data in this report is from direct measurement of the MSK5971KRH response to irradiation, but is indicative of the response of both device types.
■MIL-STD-883 Method 1019.7 and ASTM F1892-06 were used as guidelines in the development and implementation of the total dose test plan for the MSK5971KRH series.
●Summary
■Reference voltage exhibited the most significant shifts due to irradiation. The reference voltage decreased with each successive dose. It is important to note however, that all devices maintained post irradiation output tolerance levels up to 150 Krad(Si).
■Line and load regulation shifts were very small and stayed within pre-irradiation limits throughout testing.
■Dropout voltage showed a slight increase, but also stayed within pre-irradiation limits up to 150 Krad(Si).
■Current Limit decreased by approximately 2.5 percent at 100 Krad(Si). .
