Radiation Tolerant Optocoupler
66223-001
The 66223 optocoupler consists of an 850 nm GaAlAs LED optically coupled to a photodiode detector driving a radiation tolerant transistor. Test studies have proven this configuration to be even more tolerant to both proton and total dose radiation than configurations using a 660 nm LED. The 66223 optocoupler is packaged in a hermetically sealed TO-5 and is a pin for pin replacement for the 4N49. This device can be supplied to customer specifications as well as tested in accordance with MIL-PRF-19500/548.
