Hi-Reliability Optically Coupled Isolator 3C91C, 3C92C (TX), 3N243, 3N244, 3N245 (TX), 3N262 Features: TO-72 hermetically sealed package 1 kVDC electrical isolation High current transfer ratio TX devices processed to MIL-PRF-19500 Description: Each device is a high reliability optically coupled isolator that consists of an infrared emitting diode and a NPN silicon phototransistor which are mounted in a hermetically sealed TO -72 package. The 3C91C and 3C92C have a 935 nm wavelength, whereas the 3N243, 3N244, 3N245 and 3N262 have an 880 nm wavelength. All devices have 0.50 (12.70 mm) leads. Electrical characteristics vary. TX devices are processed to OPTEK s military screening program patterned after MIL -PRF-19500. Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data. Contact your local representative or OPTEK for more information.
