The OLS049 is specifically designed for high-reliability 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 hermetic, 4-pin leadless chip carrier (LCC) package.
Electrical parameters are similar to the JEDEC registered 4N49U optocoupler, but with better CTR degradation characteristics due to radiation exposure. The OLS049 has 100 percent high reliability screened parts available.
The device mounting for the OLS049 is achieved with reflow soldering or conductive epoxies.
