OLC049 Radiation-Tolerant, Phototransistor Surface-Mount Optocoupler

Description

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.
