OLS2249

Dual Channel, Radiation Tolerant, Phototransistor Hermetic Surface Mount Optocoupler

The OLS2249 is specifically designed for high-reliability applications that require optical isolation in radiation environments such as gamma, neutron, and proton radiation with high current transfer ratio (CTR) and low saturation VCE. Each optocoupler channel consists of an LED and N-P-N silicon phototransistor that is electrically isolated, but optically coupled inside a hermetic 8-pin leadless chip carrier (LCC) package.

The OLS2249 has 100 percent high-reliability screening parts available. Contact us for more details.
