OLS2449
Dual Channel, Radiation Tolerant, Phototransistor Hermetic Surface Mount Optocoupler
The OLS2449 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 electrical parameters are similar the JEDEC registered 4N49U optocoupler, but with a higher CTR and better CTR degradation characteristics due to radiation exposure.
The OLS2449 has 100 percent high-reliability screening parts available. Contact us for more details.
