OLC049

Radiation-Tolerant, Phototransistor Surface-Mount Optocoupler


The OLC049 can be used for large satellite constellation applications that require optical isolation in radiation environments such as gamma, neutron, and proton radiation with a high Current Transfer Ratio (CTR) and low saturation VCE. Each optocoupler consists of an LED and N-P-N silicon phototransistor that is electrically isolated, but optically coupled inside a non-hermetic, four-pin Leadless Chip Carrier (LCC) package.

The hermetic surface-mount variant of the OLC049 optocoupler is available as the OLS049, both in a non-screened catalog version as well as a high-reliability screened version.
