OLC049

Radiation-Tolerant, Phototransistor Surface-Mount Optocoupler


Please note: OLC049 is being discontinued and is not recommended for new designs.

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.
