Hi-Reliability Optically Coupled Isolator 3C91C, 3C92C, 3N243, 3N244, 3N245, 3N261, 3N262, 3N263 (TX, TXV) Features: r  TO-72 hermetically sealed package Օ 1 kVDC electrical isolation  High current transfer ratio Օ TX and TXV devices processed to MIL-PRF-19500 _I \ 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 3C291C and 3C292C have a 935 nm wavelength, whereas the 3N243, 3N244, 3N245, 3N261, 3N262 and 3N263 have an 880 nm wavelength. All devices have 0.50" (12.70 mm) leads. Electrical characteristics vary. The 3N261TX, 3N262TX and 3N263TX devices are similar to JEDEC registered optically coupled isolators. TX and TXV 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 (dgradation) data. Contact your local representative or OPTEK for more information.
