OPTOELECTRONIC PRODUCTS DIVISION •••• 725 E.Walnut St., Garland, TX 75040 •••• (972)272-3571 •••• Fax (972)487-6918 www.micropac.com E-MAIL: OPTOSALES @ MICROPAC.COM 66228 3C91C TYPE PROTON RADIATION TOLERANT OPTOCOUPLER OPTOELECTRONIC PRODUCTS DIVISION 09/22/2010 Features: • High Reliability • Base lead eliminated for improved noise immunity • Rugged package • Stability over wide temperature • +500 V electrical isolation Applications: • Eliminate ground loops • Level shifting • Line receiver • Switching power supplies • Motor control DESCRIPTION The 66228 optocoupler consists of an 850 nm GaAlAs LED optically coupled to a silicon planar phototransistor. This LED has proven to be highly tolerant to proton radiation and to be more tolerant of operating temperatures over 100°C than the more commonly used 660 nm LED. The optocoupler is built on a TO-72 header. The anode of the LED is electrically connected to the case. The internal base connection has been eliminated for improved noise immunity.
