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
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 (degradation) data.
Contact your local representative or OPTEK for more information.
