Characterization of Low Dose Rate Ionizing Radiation Effect on the Micropac 66266-303 Optocoupler

This paper reports Low Dose Rate (LDR) radiation test results for the Micropac 66266–303 optocoupler and presents LDR effects on the device Current Transfer Ratio (CTR). CTR degradations are also compared between 66266 and 66224 (JANSR4N49) optocouplers.
