Hi-Reliability Optically Coupled
Isolator
3C91C, 3C92C, 3N243, 3N244, 3N245, 3N261,
3N262, 3N263 (TX, TXV)
Features:
TO-72 hermetically sealed package
1 kVDC electrical isolation
High current transfer ratio
TX and TXV 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, 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 (degradation) data.
Contact your local representative or OPTEK for more information.
