Proton Radiation Tolerant Optocoupler (Pin-For- Pin Replacement For 4N49)

66227-001
The 66227 Optocoupler consists of an 850nm GaAIAs LED optically coupled to a phototransistor mounted in a hermetic TO-5 package. Test studies have shown this LED to be even more radiation tolerant than the 660nm LED typically used in radiation tolerant applications. Available in commercial or screened levels.
