Paper Abstract

A method to qualify Commercial-Off-The-Shelf optocouplers for use in a space-based application is presented. Emphasis is placed on quantifying the degradation from total dose at several operational temperatures for use by Design Engineers in estimating worst-case circuit performance. Total dose and higher temperature result in changes to the optocoupler's current-transfer-ratio depending on the amount of forward bias in the LED. These changes may require redesign or modification of the optocoupler circuit within a system.
