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 ra o
TX and TXV devices processed to MIL-PRF-19500
DescripƟon:
Each device is a high reliability op cally 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 characteris cs vary. The 3N261TX, 3N262TX and 3N263TX devices are similar to JEDEC
registered op cally coupled isolators.
TX and TXV devices are processed to OPTEK’s military screening program paƩerned aŌer MIL-PRF-19500.
Please refer to ApplicaƟon BulleƟns 208 and 210 for addiƟonal design informaƟon and reliability (degradaƟon) data.
