Sensing and Control Hi-Reliability Optically Coupled Isolator 3C91C, 3C92C, 3N243, 3N244, 3N245, 3N261, 3N262, 3N263 (TX, TXV) Features: TO-72 herme cally sealed package 1 kVDC electrical isola on High current transfer rao TX and TXV devices processed to MIL-PRF-19500 Descrip on: Each device is a high reliability opcally coupled isolator that consists of an infrared emi ng diode and a NPN silicon phototransistor which are mounted in a herme cally sealed TO-72 package. The 3C91C and 3C92C 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 characteriscs vary. The 3N261TX, 3N262TX and 3N263TX devices are similar to JEDEC registered op cally coupled isolators. TX and TXV devices are processed to OPTEKs military screening program pa erned a er MIL-PRF-19500.
