This series of high-reliability optically coupled isolators consists of an infrared emitting diode and an NPN silicon phototransistor housed in a hermetically sealed TO-72 package. The 3C91C and 3C92C models operate at a 935 nm wavelength, while the 3N243, 3N244, 3N245, and 3N262 models operate at 880 nm. All devices feature 0.50" (12.70 mm) leads. TX variants are processed to OPTEK's screening program, patterned after MIL-PRF-19500. These isolators provide high-voltage isolation, electrical isolation in challenging environments, and are suitable for industrial, medical, and office equipment.
