66225 TO-72 RADIATION TOLERANT OPTOCOUPLER MICROPAC WITH 850 nm LED OPTOELECTRONIC PRODUCTS DIVISION 05/21/03 Features: Applications: • • • • • • • • • Designed to meet or exceed MIL-PRF-19500 radiation requirements High Current Transfer Ratio - 200% typical 500Vdc electrical input to output isolation Base lead provided for conventional transistor biasing Eliminate ground loops Level shifting Line receiver Switching power supplies Motor control DESCRIPTION The 66225 optocoupler consists of an 850 nm GaAIAs LED optically coupled to a photodiode detector and a 2N2222 transistor all mounted in a hermetic TO72 package. This configuration has proven to be highly tolerant to both proton and total dose radiation. The 850 nm LED has proven to be more tolerant of operating temperatures over 100°C than the more commonly used 660nm LED.
